Additive vs. redundant properties of theory in the advancement of weight-control behaviors within community-based obesity treatments in lower- to lower-middle income women

BackgroundObesity is a growing epidemic with non-surgical/non-pharmacological interventions having only nominal and transient effects on excess weight. Those persistent shortcomings are associated with minimal understandings of impacts of treatment-associated changes in psychological variables and their relationships. Women of lower incomes have high rates of obesity and might have increased difficulties accessing evidence-based programs.MethodsWomen with obesity of lower- to lower-middle incomes participated in 6-month community-based treatments in the United States emphasizing either self-regulatory skills development (behavioral methods group: n = 63) or typical education in exercise and healthy dietary practices (education group: n = 48).ResultsThere were significant 6-month improvements in self-regulation, self-efficacy, mood, physical activity/exercise, dietary behaviors, and weight in both groups. All improvements were significantly greater in the behavioral group. Based on the incorporation of multiple behavioral theories, separate multiple regression models were fit for prediction of the weight-loss behavior changes. Stepwise entry of changes in self-regulation, self-efficacy, and mood each significantly contributed to the explained variance in physical activity/exercise change. Change in self-efficacy was most relevant in the prediction of change in dietary behaviors. Change in physical activity/exercise was significantly related to change in dietary behaviors; however, a regression analysis indicated that only physical activity/exercise change was a significant independent contributor to the overall accounted-for variance in lost weight.ConclusionBy incorporating key tenets of social cognitive theory, self-efficacy theory, self-regulation theory, coaction theory, and the mood-behavior model in an additive manner, suggestions and emphases for addressing psychological variables for improved weight-loss behaviors within scalable obesity treatments were advanced.

Self-regulatory and self-efficacy mechanisms of weight loss in women within a community-based behavioral obesity treatment.

Given the traditional methods of treating obesity through education on controlling eating and increasing exercise have largely failed beyond the very short term, a more intensive focus on psychosocial correlates of those weight-loss behaviors has been suggested. Multiple behavioral theories incorporate self-regulation, self-efficacy, and mood; however, their interrelations and effects over both the short and long term within cognitive-behavioral obesity treatments remain unclear. Within a novel community-based program with women with obesity who had either low (n = 29) or high (n = 71) mood disturbance scores, there were significant improvements in exercise- and eating-related self-regulation and eating-related self-efficacy-primary targets of that intervention-with no significant difference in those changes by mood disturbance grouping. Changes in the summed exercise- and eating-related self-regulation scores significantly mediated relationships between changes in eating-related self-efficacy and weight (over both 6 and 12months). There were similar results with mediation assessed via the extent exercise-related self-regulation carried over to eating-related self-regulation. In both of those models a reciprocal relationship between self-regulation and self-efficacy changes was indicated. In serial multiple mediation equations, paths of changes in exercise-related self-regulation → eating-related self-regulation → eating-related self-efficacy → weight were significant. However, paths were not significant when change in self-efficacy was entered as the predictor (initial) variable. Findings suggest viability in first focusing on exercise-related self-regulation, then eating-related self-regulation, in the course of increasing self-efficacy and probabilities for inducing enough sustained weight loss to improve obesity-associated health risks. Benefits of field-based research findings generalizing to weight-management applications were suggested.

Theory-Driven Behavioral Obesity Treatment and Carry-Over of Exercise-Related, to Eating-Related, Self-Regulation: Effects on Short- and Long-Term Weight/Waist Circumference Reductions.

The predominant method for treating obesity has been suggesting and providing information on a controlled diet and, to a lesser extent, increased exercise. That approach has largely failed beyond the short term for many decades as obesity rates continue to rise. Therefore, leveraging improvements in psychosocial correlates of weight-loss behaviors has sometimes been suggested instead. The aim of this study was evaluation of targeted improvements in self-regulation and self-efficacy within a theoretically derived weight-loss program. Women with obesity (N = 103) participated in a year-long community-based program emphasizing self-regulatory skills development to counter lifestyle barriers/challenges to first exercise, then controlled eating. Within a structured treatment protocol administered by community facility employees-and based on tenets of social cognitive theory, self-regulation theory, self-efficacy theory, and coaction theory-self-regulatory skills were initially developed to foster adherence to exercise. Those skills were then adapted to promote eating-behavior changes, emphasizing fruit and vegetable intake. Improvements in measures of exercise self-regulation, eating self-regulation, and self-efficacy for controlling eating, their corresponding behaviors, and weight and waist circumference were significant. Greater within-participant carry-over of changes in exercise self-regulation to eating self-regulation was significantly associated with more weight and waist circumference reductions over both 6 and 12 months. Change in eating-related self-efficacy significantly mediated those relationships. The mean weight reduction of approximately 6% indicated positive effects on obesity-related health risks. The community-based setting indicated potentials for large-scale dissemination of theory- and evidence-driven behavioral obesity treatments focused primarily on self-regulatory skills development.

Impacts of early psychological changes on correlates of weight-loss maintenance: Seeking increased precision for sustained behavioural obesity treatment effects.

Obesity is an increasing worldwide health issue. In affluent English-speaking countries, obesity ranges from ~28% (Australia) to ~42% (United States) of the adult population. Enabling weight loss beyond an initial 6 months is an unresolved challenge. Women with obesity participated in community-based obesity treatments incorporating either cognitive-behavioural methods emphasizing self-regulatory skills development (n = 106) or typical information/education processes (n = 47). Psychosocial, behavioural, and weight changes were measured. Significant overall improvements in exercise-related self-regulation and self-efficacy, mood, physical activity/exercise (PA/exercise), diet, and weight were found from baseline-month 6 (weight-loss phase) and baseline-month 12, but not from months 6-12 (weight-loss maintenance phase). Significantly greater improvements were found in the cognitive-behavioural group. Within the weight-loss phase, changes in both PA/exercise and diet significantly contributed to the explained variance in weight loss, whereas within the weight-loss maintenance phase, only change in PA/exercise was a significant predictor. There was no significant relationship of weight loss across phases. Months 6-12 change in PA/exercise significantly mediated relationships of changes in self-regulation→weight, mood→weight, and self-efficacy→weight. Earlier scores and score changes in mood and self-efficacy significantly impacted the subsequent parallel relationships. Cognitive-behavioural methods affect psychosocial changes leading to initial changes in diet, PA/exercise, and weight. Those changes then impact subsequent changes in PA/exercise-a primary malleable correlate of maintained weight loss. SO WHAT?: This research extended previous findings to better-inform behavioural obesity-treatment foci to address the pervasive public health problem of attaining and sustaining weight loss. Findings related to PA/exercise will help impact health-promotion outcomes.

Clinical evaluation of the efficiency of combined phytotherapy in the postoperative period in patients with uterus cancer

As it is well known, that operative procedures which influence on ovary functions and relieve the patient of some suffering and danger from diseases, are realized by pronounced changes in hormonal self-regulation, homeostasis disturbance, deep psycho-emotional disorders, which leads to a change in the quality of life, an increased risk of long-term complications development (cardiac vascular pathology, osteoporosis, etc.).Some authors explain the changes in neurovegetative and endocrine homeostasis after hysterectomy not only by the insufficient development of collateral blood flow, but also by the removal of one of the links of the self-regulatory system – APUD – the uterine system, which causes the disorders in hypothalamic-pituitary-ovarian relationships. Menopausal symptoms with the appearance of neurovegetative, psychoemotional disorders, urological disorders, sexual dysfunction, as well as metabolic manifestations do not always provide an opportunity to assess the parameters of a woman’s health, which are combined into the concept of quality of life.The article presents the results of a study on the use of Cimicifuga racemosa for the treatment and prevention of post-hysterectomy syndrome in patients with uterine cancer in the postoperative period.The objective: to study the clinical effectiveness of the drug, which contains the estrogen receptor modulator Cimicifuga racemosa, in patients after surgical treatment for hormone-dependent uterine tumors.Materials and methods. The study included 50 uterine cancer patients after hysterectomy. 30 patients (main group) of them had rehabilitation therapy in the postoperative period (postoperative antibacterial prophylaxis, analgesic therapy, vaginal sanation) and, starting from the second month, they additionally received a herbal preparation with an extract of Cimicifuga racemosa, 1 tablet 1 time a day for 4 months.The control group included 20 women who received only rehabilitation therapy after surgery.Quality of life was assessed after 6 months of therapy based on a comprehensive assessment using the modified MENQOL scale and the study of such important indicators as energy, sleep, emotional reactions, social isolation, physical activity, and pain.All types of statistical processing were performed using the standard package «Statistica for Windows – 10».Results. The use of selective combined herbal therapy of the post-hysterectomy syndrome in patients with hormone-dependent tumors after 6 months of treatment leads to a decrease in the frequency of hot flashes by 63.3%, profuse sweating by 63.4%, sleep disturbances by 43.3%, increased fatigue by 40.0%, depressive disorders – by 36.7% and irritability – by 33.3%.Additional use of the herbal preparation with Cimicifuga racemosa extract reliably (p<0.05) reduces the manifestations of post-hysterectomy syndrome, improves the quality of life, is well tolerated and has no side effects.Conclusions. The use of selective combined herbal therapy in the postoperative period in patients with cancer of the uterine body allows to reliably improve the quality of life of patients and reduce the clinical manifestations of post-hysterectomy syndrome, which is especially relevant in patients with cancer of the uterine body, for whom replacement hormone therapy is contraindicated. Selective herbal therapy is well tolerated by patients and can be used for a long time.

Obesity treatment-associated transfer of exercise-related self-regulation to eating-related self-regulation changes in women

ABSTRACT Obesity in the United States has risen to 42 percent of its adult population and is similarly problematic in many other countries. Although the U.S. government has provided education on healthy eating and the need to exercise regularly, behavioral obesity treatments have largely failed to sustain reductions in weight. Self-regulation, and the incorporation of exercise for its psychological impacts on eating, has sometimes been targeted. While there has been sporadic investigation into the carry-over of exercise-related self-regulation to eating-related self-regulation, the present aim is to further inquiry in that area to inform future treatment content for improved effects. Women enrolled in community-based obesity treatments with either a self-regulation (n = 106) or education (n = 54) focus were assessed on changes in exercise- and eating-related self-regulation, negative mood, completed exercise, and weight. Improvements were significantly greater in the self-regulation-focused group. After controlling for initial change in eating-related self-regulation, change in that measure from Month 3 to 6 was significantly predicted by change in exercise-related self-regulation during the initial 3 treatment months. This suggested a carry-over effect. A stronger predictive relationship was associated with the self-regulation-focused treatment. In further analyses, paths from changes in exercise→negative mood→self-regulation of both exercise and eating were significant. Increase in eating-related self-regulation was significantly associated with weight loss over 6, 12, and 24 months. The self-regulation-focused group had stronger relationships, again. Findings suggested utility in targeting exercise-related self-regulation to impact later change in eating-related self-regulation, and the use of exercise-associated mood improvement to bolster participants’ self-regulation capabilities.

Behavioral and Psychosocial Mediators of the Effects of Increased Self-Regulation on Short- and Long-Term Weight Loss in Women Within Community-Based Obesity Treatments.

The aim of this study was to evaluate behavioral mediators of relationships between increased self-regulation of eating and weight loss so that findings on psychosocial correlates of treatment-associated weight change could be extended. Participants were women enrolled in 6-month community-based obesity treatments using primarily self-regulatory (SR-treatment, n = 52) or education-focused (Didactic training, n = 54) methods. Changes from baseline in self-regulation of eating, self-efficacy for controlled eating, emotional eating propensity, exercise, and the diet were first calculated. There were significant overall improvements in each psychosocial and behavioral measure, and weight. Except for emotional eating change from baseline-Month 12, improvements were each significantly greater in the SR-treatment group. Mediation of the relationships of change in self-regulation with 6-, 12-, and 24-month weight changes, by changes in self-efficacy and emotional eating, were significant, R2s = .19-.26, ps < .001. Only changes in emotional eating over 6 and 12months were significant mediators. Mediations of the same self-regulation-weight change relationships by changes in exercise and the diet were also significant, R2s = .19-.28, ps < .001, and only changes in exercise over 12 and 24months were significant mediators. Although group membership did not moderate effects on weight, substitution of sweets for the (composite) diet demonstrated it to be a significant mediator over 6 and 12months. In women with obesity, self-regulation improvement was associated with short- and longer-term weight loss through changes in emotional eating, exercise, and sweets consumption. Thus, behavioral treatments will benefit from targeting those variables.

Relationship of increased fruit/vegetable intake with reduced consumption of sweets: Psychological mechanisms and associated weight loss in women within behavioral obesity treatments

Although an increase in fruit and vegetable (FV) consumption in adults might result in reductions in their intake of sweets, there has been minimal direct testing of this. Women participated in 6-month community-based obesity treatment conditions where either their psychological skills development (n = 66) or knowledge regarding healthful eating and exercise (n = 39) was emphasized. Improvements in FV and sweets intake, eating-related self-regulation, self-efficacy for controlled eating, and negative mood were significantly more pronounced in the psychological skills group participants. Together, participants’ change in self-regulation, self-efficacy, and mood significantly mediated the relationship of their changes in FV and sweets. Within simple mediation analyses, participants’ changes in self-efficacy and negative mood were significant mediators, and their treatment group membership moderated effects on sweets. We provided suggestions for future treatments based on the present findings.

Psychosocial Predictors of Maintained Weight Loss in Women: Informing Behavioral Obesity Treatment Foci.

Behavioral obesity treatments are typically unable to facilitate meaningful weight loss beyond the short term. Implications of malleable psychosocial factors are unclear, which limits behavioral intervention contents. The current aim was to inform obesity treatments to improve their foci on psychosocial factors leading to resilient behavioral changes and maintained weight loss. Based on pre-planned analyses, women participating in a community-based obesity treatment emphasizing self-regulation and exercise, and who lost at least 3% of their initial weight (N = 89), were measured on eating-related self-efficacy, negative mood, emotional eating, body satisfaction, and self-regulating eating at baseline, Month 3, and Month 6; and on weight change over 12months. From baseline to Month 6, there was a significant overall improvement in each psychosocial variable. In separate multiple regression equations, scores at (1) Month 6, (2) change from baseline to Month 6, and (3) change from Month 3 to Month 6 were entered as predictors of maintained weight loss from Month 6 to Month 12. Using a backward elimination process, only negative mood was retained in the final Month 6 model, and significantly predicted maintained weight loss (R2adjusted = .03, p = .050). Changes in self-efficacy, mood, emotional eating, and self-regulation were retained in the final baseline to Month 6 model, and significantly predicted weight loss maintained over 12months (R2adjusted = .30, p < .001). Findings add to research on obesity treatment development by suggesting an enhanced focus on facilitating changes in self-efficacy, mood, emotional eating, and self-regulation may enhance maintenance of lost weight (or increase weight loss).

Temporal Aspects of Psychosocial Mediators of the Exercise-Weight Loss Maintenance Relationship Within Scalable Behavior-Change Treatments.

Limited knowledge of psychological correlates of weight loss is associated with continuing failures of behavioral obesity treatments beyond the short term. This study aimed to inform health professionals' obesity interventions via an increased knowledge of mediators of the exercise-weight loss maintenance relationship. Women participated in 6-month obesity treatments within community settings emphasizing moderate exercise and self-regulation skills development via primarily in-person (n = 54) or primarily written (n = 54) means. Changes in mood, self-regulating eating, and weight over 6, 12, and 24 months were assessed. A moderated mediation model was tested using the PROCESS macro instruction. Improvements in mood, self-regulating eating, and weight were significantly greater in the in-person group. The relationship between a dichotomous measure of completing at least 3 sessions of exercise per week (or not) and change in weight over 6 months was no longer significant when the mediators of changes in negative mood and self-regulation of eating were sequentially entered. Paths of exercise→negative mood reduction→eating self-regulation increase→weight loss over 6, 12 and 24 months were significant. Exercise self-regulation at Month 3 significantly moderated the mood change→eating self-regulation change relationship. Based on the identified paths, scalable obesity-treatment content and emphases were informed. This could help guide health professionals' actions concerning the management of obesity.

Abstract P466: A Culturally Tailored mHealth Lifestyle Intervention Improves Diet and Physical Activity Self-Regulation Among African Americans

Background: Physical inactivity and poor adherence to healthy eating guidelines impact cardiovascular health (CVH) outcomes in African American (AAs). Our randomized controlled trial (RCT) testing the FAITH! App, an mHealth lifestyle intervention, showed efficacy in promoting ideal CVH, particularly diet and physical activity (PA) among AAs, warranting exploration of underlying factors. Psychosocial factors (e.g., self-regulation, self-efficacy, social support) are key to healthy behavior adoption. Hypothesis: The intervention group would have greater improvements in diet and PA-related psychosocial factors than the control group after using the FAITH! App. Methods: A 2-arm cluster RCT was conducted among AAs from 16 churches in Minnesota comparing the FAITH! App intervention to a delayed intervention control group. The FAITH! App included culturally relevant, CVH-focused education modules, diet/PA self-monitoring and a sharing board. The outcomes were change in diet and PA self-regulation and self-efficacy (primary) and social support and barriers (secondary) at 6 months post-intervention. The intervention effect was assessed using linear regression. Results: Sixty-eight participants were included (71% female; mean age [SD]: 54.7 [12.6] years) ( Table 1 ). The intervention group showed a significantly greater increase in diet self-regulation [planning/tracking nutrition] (+0.66, p&lt;.03) and PA self-regulation [step count strategies] (+0.47, p=.003) than the control group. Within groups, the intervention group demonstrated significant improvements across diet and PA self-regulation measures, while the control group showed an improvement only in fruit/vegetable and grain intake. No effect was observed in self-efficacy, social support, or barriers. Conclusions: Our culturally tailored mHealth lifestyle intervention was associated with notable increases in diet and PA self-regulation, suggesting a potential mechanism by which the FAITH! App improves healthy eating and PA among AAs.

EFFECTS OF IDEA-GENERATION STRATEGIES ON VIETNAMESE EFL STUDENTS’ EXPOSITORY WRITING QUALITY AND SELF-EFFICACY

This quasi-experimental study was conducted to investigate the effects of idea-generation strategies, group discussion, and freewriting on Vietnamese EFL students’ expository writing quality. Changes in these students’ writing self-efficacy after they used the two strategies were also explored. Forty-seven EFL sophomore students of Tra Vinh University were chosen to be the participants of this study. The students were divided into two groups: experimental group 1 and experimental group 2. In the pre-writing stage, while students in experimental group 1 shared their ideas in a group discussion, students in experimental group 2 generated their ideas through freewriting. Data were collected through two writing tests including a pretest and a post-test, and a self-efficacy questionnaire delivered before and after the six-week intervention. Analysis of the test results exhibited that both group discussion and freewriting enhanced the quality of students’ texts in terms of content and organization, with group discussion resulting in better content than freewriting. Specifically, both strategies helped students’ writing self-efficacy with respect to writing ideation, writing conventions, and writing self-regulation change positively. Finally, some recommendations for future researchers are also mentioned.&lt;p&gt; &lt;/p&gt;&lt;p&gt;&lt;strong&gt; Article visualizations:&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;img src="/-counters-/edu/0778/a.php" alt="Hit counter" /&gt;&lt;/p&gt;

Interplay Among Self-Regulation Processes Over Time for Adolescents in the Context of Chronic Stress

ABSTRACT Developmental changes in self-regulation are theorized to underlie adolescents’ engagement in risky behaviors, physical health, mental health, and transition to adulthood. Two central processes involved in self-regulation, self-management (i.e. planning, concentration, and problem-solving) and disinhibition (e.g. distractibility and impulsivity) appear to develop asynchronously and may be differentially activated based on contextual factors. Using a sample identified based on exposure to chronic stressors, we investigated how changes in self-management and disinhibition affect each other over time and whether these changes occur differently for boys and girls. Youth aged 8–16 (N = 708) who attended a U.S. summer camp self-reported on components of disinhibition and self-management. Cross-lagged structural equation modeling revealed a reciprocal relationship between self-management and disinhibition, with anger coping and distractibility emerging as critical factors in shaping this relationship. Changes in concentration, planning, and problem-solving were components of self-management that drove subsequent changes in boys’ disinhibition (for girls, however, planning did not). Autocorrelations for both broad processes remained strong from year to year, indicating a high degree of stability in rank order despite the myriad of physical, cognitive and socioemotional changes that occur during adolescence. We discuss implications of the reciprocal model with a focus on the relative pliability of components from each process and strategies for shaping them. Planning, concentration and distractibility are highlighted as potential targets for intervention.

Carry-Over of Exercise-Related Self-Regulation to Eating-Related Self-Regulation in Women Participating in Behavioral Obesity Treatments

ABSTRACT Purpose: Because obesity has not responded well to instructing affected adults in healthier eating behaviors and increased physical activity/exercise, enhanced research on psychosocial determinants of those behavioral changes is needed. Intervention foci on self-regulation have been suggested, but targeted research is required. Method: Women with obesity participated in community-based treatments that were either self-regulation-focused (self-regulation emphasis group; n = 52) or typical instruction-based (education [treatment-as-usual] group; n = 54). Results: There were overall significant increases in exercise-related self-regulation, physical activity/exercise, exercise-related self-efficacy, and eating-related self-regulation that were each significantly more pronounced in the self-regulation emphasis group. Increase in exercise-related self-regulation over 3 months predicted eating-related self-regulation over 6 months; however, sequential entry of changes in physical activity and exercise-related self-efficacy significantly mediated that relationship. However, only the path from changes in exercise-related self-regulation to exercise self-efficacy to eating-related self-regulation was significant. In a revised model where change in exercise self-efficacy was the sole mediator, treatment group did not significantly moderate the exercise self-regulation to eating self-regulation change relationship, but full mediation of that relationship occurred. Conclusion: Findings indicated salience for perceived ability/self-efficacy for physical activity, over actual physical activity progress, and its role in the transfer of self-regulatory skills from an exercise to eating context. Increased eating self-regulation significantly predicted weight loss over 6, 12, and 24 months. In the self-regulation emphasis group that translated to meaningful weight loss/weight-loss maintenance of greater than 5% of initial weight. Findings contributed to an increased understanding of psychosocial-change processes within obesity treatment research.

Effects of cardiovascular exercise on eating behaviours: Accounting for effects on stress, depression-, and anger-related emotional eating in women with obesity.

Obesity remains a medical issue of great concern. Behavioural methods attempting to induce weight loss have largely failed because of a minimal understanding of stress- and depression-associated psychosocial correlates. This study extended research into the effects of exercise on weight loss through psychological pathways to improve treatments. Women with obesity (N=108), participating in an original theory-driven cognitive-behavioural treatment within community-based health promotion centres, were evaluated over 24months. Their mean scores on anxiety, depression, and anger at baseline were significantly higher than normative data from a general sample of United States women. Three serial mediation models were specified assessing mediation of the significant exercise→dietary change relationship. These yielded two significant paths: changes in exercise→anxiety→anxiety-associated emotional eating→self-efficacy→diet, and changes in exercise→depression→depression-associated emotional eating→self-efficacy→diet; and one non-significant path: changes in exercise→anger→anger-associated emotional eating→self-efficacy→diet. In a subsequent moderated moderation model, change in eating-related self-regulation moderated the relationship between changes in anxiety and anxiety-associated emotional eating, where exercise-associated self-regulation moderated effects from eating-related self-regulation. Dietary improvement was significantly related to weight loss over 6 (β=-0.40), 12 (β=-0.42), and 24 (β=-0.33) months. Findings indicated an increased treatment focus on the completion of moderate amounts of exercise for weight loss and, following that, attention to improvements in anxiety, depression, anxiety- and depression-associated emotional eating, self-efficacy for controlled eating, and the transfer of exercise-related self-regulation to eating-related self-regulation. Given the scope of the obesity problem, extensions of this research within field settings are warranted to accelerate application opportunities.

Short- and Long-Term Weight Loss Among Women Is Unrelated to Completed Exercise Within an Obesity Intervention Focused on Self-Regulation.

The aim of this study was to evaluate 1) if completed exercise amounts were associated with short- and long-term weight loss within a cognitive behavioral intervention and 2) if changes in theory-based psychosocial factors significantly explained weight change. A total of 110 women with obesity participated in a yearlong treatment focused on self-regulation and were grouped based on their amount of completed exercise and assessed on changes in weight, self-regulation, and self-efficacy. There were significant overall improvements in all study measures from baseline-month 6 and baseline-month 12. Overall weight loss means (-5.8 and -5.3 kg, respectively) did not significantly differ across groups averaging the equivalent of < 2.5; 2.6-4.5; 4.6-7.0; and > 7.0 moderate-intensity exercise sessions per week. Similarly, psychosocial improvements did not significantly differ by exercise amount grouping. Increase in exercise self-regulation significantly predicted eating self-regulation gains over both 6 and 12 months. Over the same time periods, the significant prediction of weight loss by eating self-regulation increase was mediated by change in eating self-efficacy. Results suggest attainment of government-recommended amounts of exercise are not associated with significantly greater weight loss than lower amounts of exercise within an intervention focused on self-regulation. Associations of exercise with psychosocial correlates of weight loss should be a treatment consideration.

정보활용능력과 자기조절능력이 성인학습자가 인식하는 온라인 학습효과의 종단적 변화에 미치는 영향

Objectives The purpose of this study was to identify changes in information literacy, self-regulation, and online learning effectiveness of adult learners, and to explore the structural relationship between the three variables. Methods A potential growth model was used by using data surveyed in 2014 (9th), 2016 (10th), 2018 (11th), and 2020 (12th) of the Korean Education Longitudinal Study 2005 (KELS 2005). The trend of change over time and the longitudinal relationship was verified. Results As a result of examining the trend of change over time, the average of information literacy, self-regulation, and online learning effectiveness did not change significantly, and the average of online learning effectiveness was relatively high. In addition, both information literacy and self-regulation statically predicted the initial value of the online learning effectiveness, and the rate of change was also significantly predicted. Finally, it was found that information literacy was greater than self-regulation in terms of the influence on the longitudinal change of online learning effectiveness. Conclusions Discussions and suggestions were presented on the significant effects of information literacy and self-regulation on the longitudinal changes in online learning effectiveness of adult learners. To ensure stable online learning effectiveness, prior training to improve competencies such as information literacy and self-regulation is required from the beginning, and support is especially required so that learners can acquire and adapt to new technologies. Through the results of this study, it will be possible to seek ways to develop information literacy and self-regulation skills to increase the effectiveness of online learning in a situation where the importance and application fields of online learning are expanding.

Self-determination theory and the smoking cessation process: Daily electronic self-reports can identify the initiation of quit attempts

ObjectivesTo examine the motivational predictors of the smoking cessation process at the between-persons and within-persons levels. MethodsMediation analyses were conducted on self-report data (N = 236) that were collected using interval contingent sampling over a 39-day study period. ResultsThere was a high rate of attrition, as nearly 50% of participants were lost to follow-up. There were credible indirect effects of autonomous self-regulation on smoking behavior on the next day and seven-day abstinence through perceived competence and medication use. At the between-persons level, these models explained 17% of the variance in smoking behavior on the next day and 31% of the variance in seven-day abstinence; at the within-persons level, these estimates were 39% and 57%, respectively. ConclusionsDay-to-day changes in autonomous self-regulation, perceived competence, and medication use are important initiators of the smoking cessation process. Practice implicationsSmokers might be more likely to make a quit attempt if practitioners “tune into” the day-to-day fluctuations of their patients’ motivation for stopping smoking, perhaps using an electronic platform to assess and compare smokers’ current reports to their previous experiences. Such “motivational attunement” can afford practitioners an opportunity to provide need support when patients are willing and able to initiate a quit attempt.

Theory to treatment to theory: Evolving a community-based obesity intervention

Within weight-loss treatments, a better understanding of psychosocial correlates of exercise and controlled eating is required to improve lagging outcomes. Within this two-phase study, women with obesity participating in community-based treatments with educational (Phase 1 n = 57, Phase 2 n = 44) and behavioral (Phase 1 n = 80, Phase 2 n = 53) formats were contrasted on psychosocial variables over 3 and 6 months and their interrelations based on the mood-behavior-model and coaction theory. Phase 1 findings informed curricular extensions in Phase 2. In Phase 1, there were significant overall improvements in total mood disturbance, self-regulation of exercise, self-regulation of eating, and weight, which were more pronounced in the behavioral vs. educational format group (−3.5 % vs. −1.4 % weight loss, respectively). Mediation analyses indicated that change in self-regulation of exercise mediated the prediction of change in self-regulation of eating by mood change. Phase 2 findings were similar; however, effect sizes were greater (−6.2 % vs. −2.9 % weight loss, respectively). Within both phases, increased self-regulation of eating significantly predicted weight reduction. Paths from changes in mood→self-regulation of exercise→self-regulation of eating suggested future program attention focus on treatment-associated mood change reinforcing self-regulation, and self-regulation generalizing from an exercise to eating context. Methods of progressing treatment curricula via theory-testing were suggested.

Indirect Effect of Self-Regulated Exercise on Mood Through Self-Efficacy Changes

To improve deficient long-term effects, an improved understanding of psychosocial factors occurring within behavioral obesity treatments is required. The aim of this study was to suggest paths from changes in self-regulation toward reduced negative mood to inform the direction of more comprehensive investigations and treatment foci. Initially low active women (N = 87) participated in a theory-driven community-based behavioral obesity program emphasizing self-regulation and exercise. There were significant (ps < .001) improvements in exercise amounts, exercise-related self-regulation and self-efficacy, negative mood, and emotional eating during the weight loss phase of baseline–Month 6, and significant (ps < .01) deteriorations during the weight-loss maintenance phase of Month 6–Month 24. During both phases, significant paths (95% CIs [-0.31, -0.01], [-0.14, -0.01], and [-0.50, -0.01]) from changes in self-regulation toward reduced negative mood were through self-efficacy, but not exercise change itself. The mood change-emotional eating change relationships were significant (95% CIs [0.16, 0.39] and [0.19, 0.48]). Although extensions of this research are required to better understand long-term obesity intervention processes, the present findings suggest importance of treatment foci on identified psychological mechanisms of exercise treatment-mood change relationships.
