Characteristics of positive and negative effects on the quality of life of breast cancer patients

BackgroundPostoperative and ongoing treatment of breast cancer is traumatic to women with breast cancer and may lead to positive and negative psychological diseases, which can affect the prognosis of patients with breast cancer. Positive affect (PA) and negative affect (NA) significantly impact the prognosis of postoperative breast cancer patients. However, the effects of specific emotions on patient prognosis and the relationships between them are still unclear.MethodsA case–control study was conducted to investigate the characteristics of PA and NA and their effects on Quality of Life (QoL) in breast cancer patients. 442 postoperative breast cancer patients and 444 healthy women were recruited from November to December 2021. For the observation group, participants were eligible if they (1) were aged between 16 and 80 years and (2) had a confirmed pathological diagnosis of breast cancer and (3) possessed the ability to read text, voluntarily agreed to participate, provided informed consent, and cooperated with the study procedures. The control group consisted of individuals without breast cancer who met all other criteria, as stated above. Patients were excluded from the study if they (1) had severe comorbid conditions causing functional impairment or life-threatening risks or (2) suffered from mental disorders or were unconscious at the time of the study. For the control group, individuals with a pathological diagnosis of breast cancer were also excluded. All other exclusion criteria were consistent with those for the observation group. The demographic information and clinicopathological information of the participants were collected. The Positive Affect and Negative Affect Scale (PANAS) is a scale containing 20 emotional scores related to emotion and is used to assess the level of positive and negative affect. The Quality of Life Questionnaire Core 30 (QLQ-C30) was used to assess the quality of life of cancer patients in 15 domains. SPSS 24.0 was used to analyze and process the data. Independent-sample t-tests, one-way ANOVA and Pearson correlation analysis, were used to analyze PA and NA in different treatment phases. Polynomial regression and response surface analysis were conducted to assess the relationships among PA, NA, and QoL. The results were considered statistically significant at P < 0.05.ResultsCompared with healthy women, breast cancer patients had lower scores on "alert" and "distressed" but higher scores on "inspired," "scared," and "afraid." There were no significant differences in the relationships between PA and NA between patients and healthy women (P > 0.05). During the initial treatment phase, the highest proportion of patients had an NA greater than the PA (PA < NA). In the rehabilitation phase, the highest proportion of patients had PA greater than or equal to the NA (PA ≥ NA). The relationship between PA and QoL was an inverted U-shaped curve (P < 0.05), whereas the relationship between NA and QoL was a positive U-shaped curve (P < 0.05). There was an interaction effect between PA and NA (P < 0.001). The relationships among PA, NA, and QoL varied across treatment phases. In the initial treatment phase, the presence of both positive and negative affect improved QoL. In the endocrine therapy phase, excessive positive effects decrease QoL. During the rehabilitation phase, QoL improved as positive affect increased relative to negative affect.ConclusionThere are significant differences in the distributions of positive and negative effects in breast cancer patients at different treatment phases. The impact of PA and NA on QoL varies by treatment phase. Our findings have important implications for tailoring emotional interventions for breast cancer patients at different stages of treatment.

(In)Congruences in parent-adolescent reports of physical activity parenting practices: associations with adolescent physical activity

BackgroundInformant discrepancies in physical activity parenting practices (PAPP) are prevalent, but their effect on adolescent physical activity (PA) remains underexplored. This study aims to examine the relationship between the (in)congruence in the parent-adolescent reports of PAPP and adolescent physical activity (PA).MethodsSelf-administered questionnaires were used to collect perceptions on nine types of PAPP and adolescents’ PA levels from 373 Chinese parent-adolescent dyads. Multiple linear regression, polynomial regression, and Response Surface Analysis were employed to explore the relationship between parent-adolescent (in)congruence in PAPP reports and adolescent physical activity.ResultsOver half of the dyads exhibited incongruence in their PAPP reports, with parents generally reporting higher PAPP scores compared to adolescents. Neither parent-reported nor adolescent-reported punishment, pressuring, and restriction were significantly associated adolescent PA. In contrast, adolescent-reported disengagement, expectation, facilitation, monitoring, non-directive support, and autonomy support demonstrated stronger significant associations with their PA levels compared to parent-reported measures. Congruence in reporting expectation, facilitation, monitoring, non-directive support, and autonomy support was positively associated with adolescent PA, while incongruence in these practices showed inverse associations. In addition, adolescents’ gender-specific analyses demonstrated different informant effects on disengagement, monitoring, and non-directive support.ConclusionParent-adolescent (in)congruences on positive PAPP rather than negative PAPP showed significant relationships with adolescents’ PA levels, highlighting the importance of aligning parents’ and adolescents’ perceptions on positive PAPP to promote adolescent PA. Moreover, adolescent girls appear to be more sensitive to PAPP involving parents’ presence than boys.

The (in)congruence effects of organizational green compensation and employee green conscientiousness on pro-environmental behavior: evidence from China.

In past decades, the Chinese government has enacted a series of ecological policies to encourage organizations, the pivotal institutional agents implementing national policies, and employees, the crucial micro-actors engaging in ecological construction, to bring about employee pro-environmental behavior (EPEB) which is the foundation to realize nation's ecological strategies. Yet, the effectiveness of a widely adopted organizational-level green management practice "organizational green compensation" (OGC) and a typical individual-level green personality trait "employee green conscientiousness" (EGC) have been explored alone, ignoring the prevalence of various OGC-EGC combinations and failing to clarify the potential influences of OGC-EGC (in)congruence on EPEB. Our research endeavors to address this limitation by resolving the following two problems: What are the (in)congruence effects of OGC and EGC on EPEB in the Chinese context? And what is the underlying mechanism? Study 1 surveyed EGC, OGC, and EPEB among 778 subordinate-supervisor dyads and sought to test two single effects and three sets of comparisons between and within the congruence and incongruence effects using the methodology of polynomial regression and response surface analysis. Study 2 measured EGC, OGC, employee environmental commitment (EEC), and EPEB among 713 subordinate-supervisor dyads and attempted to verify the mediating role of EEC employing the block variable approach. Study 1 found that OGC and EGC independently, positively promote EPEB (ß = 0.39, p < 0.001; ß = 0.24, p < 0.001), the OGC-EGC congruence relates to higher EPEB compared to the OGC-EGC incongruence (p11 = 3.77, 95% CI = [0.71, 23.04]; p10 = - 0.65, 95% CI = [- 25.80, 0.42]; [α3 -α4 +α5] = - 0.24, 95% CI = [- 0.41, - 0.07]), the EPEB level is higher when the OGC-EGC congruence is at a high rather than low level ([α1 +α2] = 0.51, 95% CI = [0.39, 0.62]), and the EPEB level under the high-low combination is lower than that under the low-high combination ([α1-α2] = - 0.20, 95% CI = [- 0.38, - 0.02]). Study 2 further confirmed that EEC plays a mediating role during the OGC-EGC-EPEB relationships (the indirect effect = 0.14, 95% CI = [0.08, 0.20]). This research substantiates the value of OGC-EGC (in)congruence to fully understand EPEB variations such that, EPEB will be boosted (hampered) when OGC is (in)congruent with EGC; a higher congruence between OGC and EGC leads to higher EPEB, the high-low combination of OGC and EGC results in lower EPEB compared to the low-high combination, and EEC plays a mediating role in the above relationships, offering the Chinese evidence and providing theoretical and practical implications for the optimization of the OGC-EGC combinations to strengthen EPEB.

Effect of healthy dietary intention-behavior (in)consistency on depression and anxiety in the process of behavior change.

Although an increasing number of people are now committed to pursuing a healthy diet, it remains unclear how mental health changes during this process. The present study aimed to examine the combined effect of healthy dietary intention and behavior on depression and anxiety across two sub-studies. This study consisted of two parts: a cross-sectional survey (Study 1) involving 1,433 college students and an 11-day daily diary study (Study 2) with 117 college students. Polynomial regression and response surface analysis indicated that in cases of congruence, individuals' intention and behavior align at a high level and were associated with lower levels of depression and anxiety in the motivational phase but were not found similar association in the volitional phase. In cases of incongruence, individuals with high intention-low behavior tend to experience lower levels of depression and anxiety in the motivational phase. However, individuals with high intention-low behavior tend to experience higherlevels of depression and anxiety in the volitional phase. These findings not only enrich the current understanding of diet and health but also contribute to the development of holistic strategies for promoting a healthy diet.

How Empowerment Congruence Impacts Performance in Cross-Functional Project Teams: A Polynomial Regression Analysis

This study deduces the empowerment alignment in project governance through examining the roles of (in)congruence between empowering leadership and psychological empowerment in informal leadership emergence, creativity, and performance outcomes. Using the data from 210 members from 69 cross-functional project teams, the results of polynomial regression and response surface analyses indicate that the high congruence between empowering leadership and perceived empowerment enhances informal leadership emergence, then promotes creativity to facilitate performance outcomes eventually. Informal leadership emerged under the insufficient empowerment condition with higher psychological empowerment rather than the excessive empowerment condition with higher empowering leadership. The study added to the project governance body of knowledge by confirming the promoting mechanism for project performance from the congruence perspective of leader-given and subordinate-perceived empowerment.

Efficiency-centered vs novelty-centered: unpacking the impact of business model design on services in manufacturing firms

PurposeHow does business model design play a role in enabling manufacturing firms’ services? This study aims to investigate the impact of two distinct types of business model design, namely, efficiency-centered business model design (EBMD) and novelty-centered business model design (NBMD), and their effects in balanced and imbalanced configurations, on two types of services: product- and customer-oriented services.Design/methodology/approachUsing matched survey data of 390 top managers and objective performance data of 195 Chinese manufacturing firms, this study uses hierarchical regression, polynomial regression and response surface analysis to test the hypotheses.FindingsThe results show that while EBMD positively affects product-oriented services, NBMD positively affects customer-oriented services. Both types of services exert a significant influence on firm performance. Furthermore, the degree of product- and customer-oriented services increases with an increasing effort level with a balance between EBMD and NBMD. Asymmetrical, imbalanced configuration effects reveal that the degree of product-oriented services is higher when the EBMD effort exceeds the NBMD effort, and the degree of customer-oriented services is higher when the NBMD effort exceeds the EBMD effort.Originality/valueThis study enriches the understanding of designing business models to facilitate service growth in manufacturing firms, ultimately benefiting firm performance. In addition, exploring balanced and imbalanced configurations of EBMD and NBMD offers new insights into business model dual design research.

Seismic vulnerability analysis of hospitals and school buildings considering the Gaussian regression algorithm

This study combines the Gaussian regression algorithm to propose a nonlinear regression model that can be used to evaluate the seismic vulnerability of regional hospitals and school buildings. The failure features and disaster mechanisms of hospital and school buildings affected by the Jishishan (JSS) earthquake on December 18, 2023, and the Wenchuan (WC) earthquake on May 12, 2008, were reported. The samples of 252 damaged buildings (37 hospitals and 215 schools) in Dujiangyan city affected by the Wenchuan earthquake for which the author participated in the survey were collected and counted. Hospitals and school buildings were classified according to the types of reinforced concrete (RC) and masonry structures, and earthquake vulnerability probability matrices for hospital and school building clusters were established considering the actual failure probabilities. A total of 2103,213 acceleration records (from the Wenchuan earthquake) monitored by 12 real stations were selected. Using dynamic time history and response spectrum analysis methods, time history and spectrum curves were generated, considering the influence of different seismic directions. Using the developed Gaussian regression model, vulnerability comparison curves and parameter matrices considering multiple regression algorithms were generated. This paper considers the effects of the construction year and number of floors on the seismic vulnerability of hospital and school buildings. Seismic vulnerability curves and failure probability matrices were generated and established on the basis of actual structural failure probabilities. According to regression and vulnerability surface analysis, the evaluation results of the proposed model are highly consistent with actual field observations.

Hierarchical Leader-Leader Fit: Examining Authentic Leader Dyads and Implications for Junior Leader Outcomes

Leaders at lower levels do not lead in a vacuum; they must lead within the context of the leadership they experience themselves from their next higher-level leader. We propose that lower-level leaders’ thoughts and attitudes and thereby their behaviors are influenced by the level of compatibility of their own style of leadership with that of their senior leader. Drawing from person-environment fit theory, we propose the concept of hierarchical leader-leader fit by assessing the level of congruence between the authentic leadership style of senior and junior leader dyads, and the resulting effects of levels of (mis)fit on the junior leader's behaviors in the form of performance and deviance. In two samples inclusive of both business and military leaders, using polynomial regression and response surface analysis, we find that fit (misfit) between the senior leader's and junior leader's respective levels of authentic leadership in the dyad is positively (negatively) associated with the junior leader's performance and is negatively (positively) associated with the junior leader's deviance. Surprisingly, when two leaders have high levels of fit, we find similar desirable effects on performance and deviance regardless of whether both leaders practice low (low-low) or high (high-high) levels of authentic leadership. Theoretical and practical implications of the degree of fit between leaders operating at different organizational levels, and of leadership as a contextually embedded relationship are discussed.

Exploring Mianzi consciousness congruence and its impact on unethical pro-organizational behavior

BackgroundIn Chinese culture, the concept of Mianzi holds significant importance in interpersonal interactions. Mianzi represents one’s social standing, dignity, and reputation, influencing behaviors and decisions within various contexts. Mianzi consciousness manifests in two primary forms: proactive and defensive. Proactive Mianzi consciousness involves efforts to enhance one’s social image, while defensive Mianzi consciousness focuses on protecting one’s existing reputation. Analyzing the impact of the two Mianzi consciousness dimensions on individuals’ attitudes and behaviors is effective for understanding interpersonal dynamics in China. This study specifically examined the relationship between high Mianzi consciousness congruence and unethical pro-organizational behavior (UPB). UPB refers to actions taken by employees that are intended to benefit their organization but are unethical or morally questionable. By investigating how congruence in proactive and defensive Mianzi consciousness influences the likelihood of engaging in UPB, this research aimed to uncover the underlying social and psychological mechanisms driving such behavior.MethodsEmploying polynomial regression and response surface analysis method, this study developed a model that combines the proactive Mianzi consciousness and the defensive Mianzi consciousness into different Mianzi management strategies and tested the relationship between high Mianzi consciousness congruence and UPB.ResultsSample data collected at two time points one month apart supported all hypotheses. Specifically, the findings revealed that high levels of Mianzi consciousness congruence (i.e., all-around type in Mianzi management strategies) positively relate to UPB, and verified the mediation effect of external work locus of control and the moderation effect of relational psychological contract.ConclusionThis research advanced a novel, synergistic perspective on the role of social Mianzi and contributed to the localized UPB research, thus helping to find a path to prevent UPB from occurring in the Chinese sociocultural context.

Unveiling the impact of the congruence between artificial intelligence and explorative learning on supply chain resilience

PurposeDrawing upon socio-technical system theory, this study intends to investigate the effects of the congruence and incongruence between artificial intelligence (AI) and explorative learning on supply chain resilience as well as the moderating role of organizational inertia.Design/methodology/approachUsing survey data collected from 170 Chinese manufacturing firms, we performed polynomial regression and response surface analyses to test our hypotheses.FindingsWe find that the congruence between AI and explorative learning enhances firms’ supply chain resilience, while the incongruence between these two factors impairs their supply chain resilience. In addition, compared with low–low congruence, high–high congruence between AI and explorative learning improves supply chain resilience to a greater extent. Moreover, organizational inertia attenuates the positive influence of the congruence between AI and explorative learning on supply chain resilience, while it aggravates the negative influence of the incongruence between these two factors on supply chain resilience.Originality/valueOur study expands the literature on supply chain resilience by demonstrating that the congruence between a firm’s AI (i.e. technical aspect) and explorative learning (i.e. social aspect) boosts its supply chain resilience. More importantly, our study sheds new light on the role of organizational inertia in moderating the congruent effect of AI and explorative learning, thereby extending the boundary condition for socio-technical system theory in the supply chain resilience literature.

The effect of leader-team (in-)congruence in future orientation on leader’s participative leadership: the moderating role of leader workload

Purpose Prior studies have consistently treated participative leadership as a given leadership style. Conversely, this study aims to prove that participative leadership can be predicted by leaders and teams collectively, depending on leaders' work characteristics (i.e. workload). Design/methodology/approach A two-source survey was designed to collect data from a sample of 89 leader-team dyads in a trading company in a southeastern Chinese city. Polynomial regression and response surface analysis were used to test the hypotheses. Findings The leader showed more participative leadership when leader-team future orientation was congruent rather than incongruent; in the congruent situation, there was an inverted U-shaped relationship between leader-team future orientation congruence and participative leadership; in the incongruent situation, when the team's future orientation gradually exceeded the leader's, participative leadership first increased and then decreased; and leader workload positively moderated the relationship between leader-team future orientation congruence and participative leadership. Originality/value These findings theoretically respond to the call for investigating the influence of leader-team future orientation congruence on leaders’ behaviors, and in practice enlighten managers on how to encourage supervisors to involve employees in decision-making processes.

Giving It a Shot with a Different Approach: Prosocial Strategies Moderate the Joint Effects of Agentic and Communal Goals on Bullying.

This study uses polynomial regression and response surface analyses to investigate the joint effects of agentic and communal goals on bullying and the moderating role of prosocial strategies. The sample included 917 adolescents (Mage = 13.54, SD = 1.02) from rural, suburban, and urban areas in China. The findings revealed that higher agentic and lower communal goals were associated with a linear rise in bullying. Surprisingly, when both social goals were higher simultaneously, bullying followed an inverted U-shaped pattern. Furthermore, prosocial strategies moderated the joint effects of the two social goals. Adolescents who are more likely to use prosocial strategies do not show significant changes in bullying when both goals are at a higher level. In contrast, those who are less likely to do so show a linear rise in bullying, regardless of changes in social goals. This study improves our understanding and intervention of bullying behavior, emphasizing a non-pathological perspective.

Big data analytics capability and social innovation: the mediating role of knowledge exploration and exploitation

While many organizations have successfully leveraged big data analytics capabilities to improve their performance, our understanding is limited on whether and how big data analytics capabilities affect social innovation in organizations. Based on the organizational information processing theory and the organizational learning theory, this study aims to investigate how big data analytics capabilities support social innovation, and how knowledge ambidexterity mediates this relationship. A total of 354 high-tech companies in China, this study shows that big data analytics management, big data analytics technology, and big data analytics personnel capabilities all have positive effects on social innovation. In addition, both knowledge exploration and knowledge exploitation play a mediating role in this process. Furthermore, a polynomial regression and response surface analysis shows that social innovation increases when knowledge exploration and knowledge exploitation are highly consistent but declines when knowledge exploration and knowledge exploitation are inconsistent. This study not only provides new perspectives for understanding how big data analytics capabilities contribute to social innovation, complementing the existing literature on big data analytics capabilities and social innovation, but also provides important practical guidance on how organizations can develop big data analytics capabilities to improve social innovation and solve social problems in the digital age.

Social support and family resilience among Chinese people receiving maintenance hemodialysis: A polynomial regression and response surface analysis explaining psychological resilience.

Psychological resilience plays an important role in overcoming emotional distress among people receiving maintenance hemodialysis (MHD). This study aimed to investigate how social support and family resilience interact to influence psychological resilience among Chinese people receiving MHD. This was a prospective longitudinal study with three time points: baseline (T1), 3 months (T2), and 6 months (T3) later. A convenience sample of 252 participants (67.1% male; 57.6 ± 13.8 years of age) from Zhejiang Province, China, who completed baseline measures of social support, family resilience, and psychological resilience, were further assessed for psychological resilience at T2 and T3. Polynomial regression (PR) and response surface analysis (RSA) were used to analyze the data. At all time points, and in the case of agreement between social support and family resilience, the combined effect of both variables manifested as a positive linear association with psychological resilience. Instead, at baseline, and in case of disagreement, the same combined effect manifested as a negative linear relationship related to psychological resilience. The findings highlighted the importance of considering the conjoint influence of social support and family resilience when developing interventions to improve the psychological resilience of people receiving MHD.

The Association between Discrepancies in Parental Emotional Expressivity, Adolescent Loneliness and Depression: A Multi-Informant Study Using Response Surface Analysis.

Incongruent perceptions of parental emotional expressivity between parents and adolescents may signify relational challenges, potentially impacting adolescents' socioemotional adjustment. Direct evidence is still lacking and father-adolescent discrepancies are overlooked. This study employed a multi-informant design to investigate whether both mother-adolescent and father-adolescent discrepancies in perceptions of parental expressivity are related to adolescents' mental well-being, specifically focusing on loneliness and depression. Analyzing data from 681 families (mean age of adolescents = 15.5 years old, 51.2% girls, 40% only-children) in China revealed that adolescents tended to perceive paternal and maternal emotional expressivity more negatively than their parents, particularly fathers. Polynomial regression and response surface analysis showed significant links between parent-adolescent congruence and incongruence and adolescent loneliness. (In)Congruence between adolescents and mothers or fathers predicted later adolescent depression, mediated by adolescent loneliness and varied by the dimension of emotional expressivity. These findings provide insights into the roles of mothers' and fathers' emotional expressivity in shaping children's mental well-being during adolescence.

Research on the Influence of Teacher-Student Education Expectation Consistency on Students’ Physical Exercise: Based on Polynomial Regression and Response Surface Analysis

Students' physical exercise has important practical significance in enhancing students' physical health and promoting the health construction. Based on the expectation effect theory, this study explores the influence of teacher-student expectation consistency on students' physical exercise from a binary perspective. Using China Education Tracking Survey (CEPS) data, through polynomial regression and response surface analysis, it is found that: (1) There are four combinations of teacher-student educational expectation. Compared with the combination of "high-low", "low-high" and "low-low", when teacher-student educational expectation is consistent with "high-high", students' cognitive ability and students' physical exercise are higher; (2) Cognitive ability mediates the relationship between teacher-student educational expectation consistency and students' physical exercise; (3) The class atmosphere moderates the consistency of teacher-student education expectation and cognitive ability. This study employs computer technology to validate the impact of the teacher-student duality interaction on students' physical exercise through polynomial regression and response surface analysis. Through the design and development of intelligent auxiliary education system, teachers can gain better insight into students' educational expectations while promoting their engagement in physical exercise.

The influence of leader-subordinate emotional intelligence congruence on the flow experience: evidence from the liquor manufacturing industry.

Previous research has provided evidence supporting a positive correlation between emotional intelligence (EI) and flow. However, intriguing findings in the liquor manufacturing industry prompt me to consider the necessity of examining the effects of leader-subordinate EI congruence on flow. Therefore, this article begins with two questions: First, what is the impact of leader-subordinate EI congruence on flow? Second, do two distinct congruent scenarios (i.e., high-high and low-low) exhibit significant nuances that differentially influence flow? To answer these questions, this study utilizes polynomial regression and three-dimensional response surface analysis methods. A multi-source and three-phase investigation method was used to collect data from 279 subordinates and 56 leaders in the liquor manufacturing industry. Based on the person-environment (PE) fit theory, this study investigates the influence of leader-subordinate EI congruence on flow while considering leader-member exchange (LMX) as a mediator in these processes. The current study not only demonstrates a positive relationship between leader-subordinate EI congruence and LMX, but also reveals that a high-high EI matching pattern can enhance the favorable dynamics of congruence and yield higher LMX compared to a low-low matching pattern. Furthermore, this study identifies LMX as a mediator in the positive relationship between leader-subordinate EI congruence and flow. Additionally, although the incongruent scenarios are beyond the scope of this study, the findings demonstrate that a high EI subordinate paired with a low EI leader has a more detrimental impact on the LMX than a low EI subordinate paired with a high EI leader. Theoretical and practical implications are discussed.

Trust (in)congruence, open innovation, and circular economy performance: Polynomial regression and response surface analyses

Engaging partner firms in open innovation is critical to overcoming internal resource/capability constraints to achieve firm and supply chain circular economy (CE) performance, yet scholars have not examined this link empirically. Further, while researchers have repeatedly emphasized trust as a key driver of open innovation performance, little is known from a dyadic trust perspective (e.g., congruence vs. incongruence, high–high congruence vs. low–low congruence). To fill these gaps, we propose a theoretical model based on the social exchange theory (SET) and test it using a dyadic dataset of listed Chinese manufacturing firms. The results suggest that 1) rather than unilateral trust from the focal firm or its partners, trust congruence is more predictive of successful open process and product innovations, 2) regarding congruence types (low–low vs. high–high), congruence at higher levels of trust facilitates open product innovation more than low–low trust congruence; interestingly, such an effect is not significant for open process innovation, 3) open process innovation has a positive influence on the focal firm's CE performance, but its impact on supply chain CE performance is not statistically significant, and 4) open product innovation has a significantly positive impact on the focal firm and supply chain CE performance. Our findings still hold after analyzing time-lagged models and alternative measurements as robustness checks. Our study provides meaningful theoretical contributions to the literature and useful, practical insights for managing inter-organizational relationships, open innovation, and CE performance.

Associations of illness perception and social support with fear of progression in young and middle-aged adults with digestive system cancer: A cross-sectional study

PurposeWhile Fear of progression (FoP) is a natural reaction in cancer, elevated FoP can impact life quality and social function. Our study aims to explore how illness perception, social support, and posttraumatic growth influence patients' FoP. MethodsThis study enrolled 243 young and middle-aged adults with digestive system cancer at a hospital in Guangzhou from November 2022 to November 2023. In this study, the measurement instruments utilized included The Fear of Progression Questionnaire-Short Form, The Brief Illness Perception Questionnaire, The 12-item Perceived Social Support Scale, and The 21-item Posttraumatic Growth Inventory. Data was analyzed employing polynomial regression and response surface analyses. ResultsThe mean score of FoP was 35.45 ± 10.05, and 59.3% of the cancers (scores≥34) had clinically dysfunctional levels of FoP. Regarding congruence, patients' FoP was higher when the levels of illness perception and social support were both low or high than when the levels were both intermediate. Regarding incongruence, patients' FoP was lower when the level of illness perception was low and social support was high compared with when the level of illness perception was high and social support was low. Additionally, posttraumatic growth moderated the (in)congruence effect of illness perception-social support on the FoP of patients. ConclusionsLow or high illness perception-social support congruence was detrimental to the FoP of patients. Low illness perception-high social support incongruence was beneficial to patients' FoP. Posttraumatic growth can be a positive factor for enhancing the impact of low illness perception-high social support incongruence on patients' FoP.

Members' goal orientation and working alliance in group therapy: A response surface analysis.

Research suggests that a client's achievement goal orientation and alliance are important for positive treatment outcomes. However, it is currently unknown how a member's goal orientation and alliance in tandem relate to members' improvement in group therapy, despite conceptual wisdom regarding the additive effect of a high alliance and a mastery or approach goal orientation. Therefore, this study sought to examine the congruence between members' goal orientation and the member-group alliance on members' perceived improvement in group therapy. Data for this study came from 99 clients across 10 interpersonal process groups. Polynomial regression and response surface analysis were used to test the congruent and discrepant effects of members' goal orientation (i.e., approach-performance, avoidance-performance, and mastery orientation) and group alliance on their perceived improvement in group therapy. As hypothesized, members who reported congruent high group alliance and high mastery orientation or approach orientation compared to congruent low alliance and low mastery or approach orientation reported high levels of improvement in group therapy. Regarding discrepant effects, discrepant high alliance and low avoidance orientation compared to low alliance and high avoidance was positively related to improvement in group therapy, and discrepant high alliance and low approach orientation compared to low alliance and high approach was positively related to improvement in group therapy. Last, discrepant high alliance and low mastery and low alliance and high mastery were positively related to improvement in group therapy, suggesting a compensatory effect between mastery orientation and alliance on improvement.
