Family-Based Treatment for Anxiety, Depression, and ADHD for a Parent and Child.

Children with mental illness commonly live with caregivers who suffer from mental illness. Integrated mental-health-treatment approaches can provide more convenient and comprehensive care for families. This case report describes family-based treatment (FBT) for one parent/child dyad. The parent was a 37-year-old female with a history of anxiety and major depressive disorder and concern for symptoms of attention-deficit/hyperactivity disorder (ADHD). The child was an 8-year-old female with generalized anxiety disorder and concern for ADHD and behavioral problems. The parent received individual cognitive behavioral therapy (CBT) and parent management training. The child received CBT. Both also received medication management. The FBT team met regularly for coordinated treatment planning. Self-reported assessments via the Child Behavior Checklist showed meaningful improvement; anxiety decreased to nonclinical range week 12 and depression decreased to nonclinical range week 8. Clinician assessments showed improvement for both patients. Though more time intensive, FBT can yield significant improvement, particularly for children. Pragmatic approaches to treatment planning are important to minimize barriers to FBT.

A Review of Behavioral and Pharmacological Treatments for Adult Trichotillomania

Trichotillomania (TTM) is a psychiatric disorder involving chronic, recurrent urges to pull out one’s own hair, arising frequently in childhood and early adolescence. This disorder predominantly affects women and has a high co-morbidity with many other psychiatric conditions. Currently, the etiology is unknown, which makes treating TTM extremely difficult. While the epidemiology and proposed causes will be discussed briefly, the primary purpose of this review is to provide a comprehensive, updated summary of the psychological and pharmacological management options for patients diagnosed with TTM, as new clinical trial data for previously studied and novel treatments have become available within the last decade. Of the behavioral interventions, cognitive behavioral therapy (CBT) and habit reversal training (HRT) have demonstrated the greatest improvements in hair-pulling severity, with HRT showing the most efficacy for long-term maintenance of progress. Pharmacological therapies with the most success include Olanzapine, Clomipramine, and N-Acetylcysteine, though larger replication studies are needed. Selective serotonin reuptake inhibitors (SSRIs) have yielded inconsistent results in clinical trials, yet they are frequently prescribed for TTM. Naltrexone, Dronabinol, and Inositol are emerging as potential treatments, but the results suggest that additional studies are needed. Future research directions include larger placebo-controlled pharmacological trials, exploring the efficacy of combined behavioral and pharmacological approaches compared to monotherapy, and delving into the potential genetic and neurochemical contributions that may underlie TTM.

Cognitive Behavioral Therapy in Saudi Arabia: A Scoping Review on Training, Practice, and Research

AbstractAn evidence-based intervention for many psychiatric and health problems, cognitive behavioral therapy originated in the West before being disseminated globally. While Saudi Arabia is unique, in that it is at the heart of the Islamic world, it is similar to most other countries in that mental disorders are common. Nonetheless, few studies have examined cognitive behavioral therapy in Saudi Arabia. In this scoping review, cognitive behavioral therapy training, practice, and research in Saudi Arabia were explored by searching several English and Arabic databases. Various education and training programs were outlined. Moreover, cognitive behavioral therapy practice in Saudi Arabia in public and private settings was discussed. Published studies were grouped by themes into attitudes toward CBT, adaptation, and effectiveness. Recommendations for improvement are also discussed.

Training of transport drivers improves their handling of pigs during loading for transport to slaughter

Pig transport drivers’ (TDs’) handling actions are of great importance as these drivers handle a large number of finishing pigs during stressful situations. Poor handling techniques can have negative consequences for working conditions, pig welfare and meat quality. We studied the effects of a training intervention on Swedish TDs’ attitudes towards pigs and their handling actions during loading for transport to slaughter. Twenty TDs working with commercial pig transportation in Sweden were recruited and completed an attitude questionnaire. Ten of them were observed during one loading of pigs before training, and one or two loadings after training (49–265 pigs per loading), and eight of them completed the attitude questionnaire again 50–160 days after training. The cognitive-behavioural training program ProHand Pigs® was adapted and delivered to the ten TDs during a group session, followed by individual meetings. TDs’ handling actions were video recorded and summarised as binary variables per 5-s interval. Factor analysis, principal component analysis and paired t-test were conducted to investigate the effects of the training intervention on TDs’ attitudes, and mixed-effects logistic models were used to examine effects on negative and positive handling actions. Training tended to decrease TDs’ beliefs that it is important to move pigs quickly (P = 0.095). Training decreased the odds of a ‘moderately strongly negative’ action by 55% (P = 0.0013) and increased the odds of a ‘positive’ action by 97% (P < 0.0001). This study provides valuable insights into the possibilities to improve TDs’ handling actions, and implications for pig welfare during slaughter transport. The study supports previous findings that the attitudes and behaviour of handlers can be improved by cognitive-behavioural training. While our previous research has shown reciprocal relationships between TDs’ actions and pig behaviour, further research on TDs’ attitudes towards handling that underlie the nature of their behaviour when handling pigs is necessary to fine-tune the cognitive-behavioural training program applied in the present study.

국내 온라인 기반 우울 완화 프로그램 효과에 대한 메타분석

Objectives This study attempted to examine the effectiveness of domestic online-based depression relief pro-grams using meta-analysis methods.&#x0D; Methods For this purpose, a total of 13 papers that met the analysis criteria were selected among domestic on-line-based depression relief program studies in which the general population, adolescents and adults with de-pressive symptoms, and the elderly participated until 2022. The random effect model was selected to calculate the overall average effect size, average effect size according to mediating variables, and average effect size ac-cording to dependent variables other than depression.&#x0D; Results As a result of calculating the effect size of the papers subject to analysis, the overall average effect size was 0.6, which was medium size. Looking at the average effect size according to the mediating variable, the study subjects had an effect regardless of the clinical group excluding the general group in terms of depression level, presence or absence of facility use, dementia, and cognitive function. The operating method was found to be most effective when the total number of sessions was less than 10, the number of sessions per week was once a week, the implementation period was 8 weeks or less, and the time per session was between 30 and 60 minutes. Regarding content types, the effect size for Internet web and virtual reality was medium, and mobile applications were not significant. The effect size by program type was medium for cognitive behavioral therapy, cognitive train-ing and cognitive rehabilitation therapy, and convergence therapy. Among convergence treatments, programs combining cognitive behavioral therapy and interpersonal therapy appeared to be the most effective, and the aver-age effect size for dependent variables other than depression showed that all emotion-related variables were ef-fective, but the effect size for social skills was insufficient. It is worth paying attention.&#x0D; Conclusions These results are meaningful in providing basic data on an effective domestic online-based depres-sion alleviation program and suggest directions for follow-up research.

Negative self‐reference as a component of subthreshold psychotic symptoms in clinical high‐risk youth

AbstractAimSchizophrenia is a leading cause of disability worldwide; early detection and intervention are critical. Early in their illness, individuals at clinical high‐risk (CHR) for psychosis have subthreshold psychotic symptoms that are often derogatory and self‐directed. We hypothesized that CHR participants with negative self‐reference (NSR) as a component of subthreshold psychosis would also have higher levels of social anxiety and depression, lower self‐esteem and lower social/role/global functioning as compared with CHR participants without NSR.MethodsOne hundred and sixty‐eight participants from the National Institute of Mental Health (NIMH) funded Regroup Cognitive Behavioural Social Skills Training (CBSST) study were included. Clinical vignettes that included the Scale of Psychosis‐Risk Symptoms were coded categorically to indicate whether NSR was present. t‐tests were used to determine the association between NSR, symptom, and functional measures.ResultsParticipants with NSR demonstrated significantly more social interaction anxiety (p &lt; .001), negative beliefs about the self (p ≤ .001), defeatist beliefs (p &lt; .05), depressive symptoms (p &lt; .05) and positive symptoms (p &lt; .005). There were no significant differences in social self‐efficacy, positive or negative beliefs about others, positive beliefs about the self or psychosocial functioning between the two groups.ConclusionsClinically significant differences were found between CHR participants with and without NSR, suggesting that this may be a useful factor to identify and address. Follow‐up studies are needed to determine whether NSR responds to CBSST and whether or not its resolution would be associated with improvement in other symptom domains.

LESSONS LEARNED DEVELOPING A NUTRITIONAL ADHERENCE INTERVENTION FOR DEMENTIA PREVENTION: A QUALITATIVE ANALYSIS

Abstract Lifestyle interventions show considerable promise in delaying the onset and reducing risk for Alzheimer’s disease and related dementias (ADRD). Unfortunately, scalable interventions that address issues of long-term adherence have not been adequately developed or disseminated. Especially important for this effort is iterative evaluation and adaptation of interventions using participant feedback throughout the development process. Using the NIH ORBIT model for behavioral intervention development, our team has established the proof-of-concept (N=9) and pilot tested (N=58) a Mediterranean ketogenic nutrition (MKN) adherence program for older adults at risk for ADRD. This program incorporates motivational interviewing strategies and cognitive behavioral skills training to enhance uptake and long-term adherence to MKN. For each of these pilots, participants completed exit interviews at the conclusion of the 6-week, group intervention and 3-months post-intervention. Qualitative and quantitative data on the acceptability of the program, as well as detailed participant feedback about their experience and recommendations for improvements were collected. While quantitative data demonstrate high acceptability, thematic analysis of qualitative interviews demonstrate a range of recommendations for enhancing and refining important components of the intervention that will be necessary for future scaling and dissemination. We discuss important themes, future directions of this work, and implications for lifestyle intervention development more broadly.

Impact of a cognitive behavioural therapy training program on family physician practices: Cross-sectional study in Norway.

To investigate changes in FPs' self-reported clinical practices after participation in a comprehensive 1-year cognitive behavioural therapy (CBT) training course. Cross-sectional study. Norway. Family physicians. Impact of the CBT training course on FPs' delivery of CBT to patients and their use of referral to specialized mental health care providers. Of the 217 FPs who had participated in the training course between 2009 and 2016, 124 completed the survey (response rate=57.1%); 99.2% of participating FPs reported using CBT tools daily in patient consultations, more than three-quarters reported changing the way they organized their workdays to accommodate CBT, and 75.0% reported using structured CBT consultations at least monthly after completing the course. The most common patient groups receiving structured CBT were those experiencing mild or moderate depression (22.8%), anxiety disorders (30.4%), or a combination of an anxiety disorder and depression (43.5%). The odds of making fewer referrals to specialized mental health care providers were 5.4 times higher among FPs who used Socratic questioning (P=.02), 4.7 times higher among those who provided consultation summaries (P=.01), and 3.3 times higher among those who had participated in a refresher course (P=.05). Comprehensive training in CBT promotes the use of CBT tools and strategies in family practice. Further longitudinal research (ideally randomized controlled studies) on patient outcomes related to CBT provided in family practices is required.

Remotely-administered resilience and self-compassion intervention targeting loneliness and stress in older adults: a single-case experimental design

Objectives Loneliness and chronic stress are prevalent issues for older adults that have been linked to adverse health outcomes. We conducted a remote resilience and self-compassion intervention targeting loneliness and chronic stress. Methods This study utilized a multiple-phase-change single-case experimental design with three consecutive 6-week phases: control, intervention, follow-up. Assessments and biomarker collection (blood pressure, inflammation, sleep actigraphy) were conducted at each phase. Participants completed a 6-week remotely-administered resilience and self-compassion intervention using techniques from cognitive behavioral therapy and resilience training. Repeated measures ANOVAs were conducted over the 12-week period from control (week 0) to intervention completion (week 12) and over the 18-week period from control (week 0) to follow-up (week 18) in supplemental analyses. Results Participants reported a reduction in stress (p < 0.001; ηp 2 = 0.15), depression (p =  0.02; ηp 2 = 0.08), and loneliness (p = 0.003; ηp 2 = 0.18), and an increase in self-compassion (p  =  0.01; ηp 2 = 0.13) from control to intervention completion (weeks 0−12). Post-hoc tests revealed that stress reduced significantly during the intervention phase (weeks 6−12) and loneliness reduced significantly during the control phase (weeks 0−6). Some improvements in blood pressure, inflammation, and sleep quality were noted in a subsample of participants. Conclusion Findings indicate that our remote resilience and self-compassion intervention for older adults targeting loneliness and chronic stress was efficacious.

Effects of Animated Movies on the Aggression and Behavior Performance of Primary School Students and Their Control Using a Cognitive Behavioral Anger-Control Training (CBACT) Program.

This work is a combination of two studies, Study I and Study II, which aimed to examine the impact of animated movies on the aggression and behavioral performance of primary school students, as well as their control using the CBACT program. In Study I, the influence of animated movies on 300 students from ten primary schools in Pakistan with gender differences (50% male), family systems, and viewing time duration was examined. This study was performed on 7- to 9-year-old children on four subscales of the Buss-Perry aggression questionnaire (BPAQ), three subscales of the child behavior questionnaire (CBQ), and toy selection. Following that, in Study II the CBACT intervention was applied to aggressive students (n = 46) selected from Study I. Students were randomly divided into CBACT treatment (50%) and control groups. The results of Study I indicated that violent animated movies had a greater impact on the aggressive behavior of male students than on that of females, while girls were more affected by watching nonviolent movies. Furthermore, male viewers from nuclear families and females from joint families showed more aggressive problems. It was also observed that aggression in students significantly increased (p < 0.001) with increasing viewing animation time duration (10 to 30 min). The results of Study II showed that aggression in the treatment group was significantly reduced (p = 0.000) with the CBACT program but remained constant for the control group. The findings of Study I showed that violent animation is strongly linked with aggression and behavioral performance in primary school students. The CBACT program in Study II indicates that students may not be completely eliminated from watching violent movies, but their aggression levels were reduced when they watched animated movies. Therefore, the CBACT program opens a new window into behavioral problem treatment, which is casually influenced by violent media.

[Expert consensus on the diagnosis and treatment of adult attention deficit hyperactivity disorder in China (2023 Edition)].

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in school-age children, with 30%-50% persisting into adulthood. In addition, adult ADHD patients have more comorbidities, are more difficult to identify, and have a wider range of impairments on individual function, thereby leading to more serious adverse effects on medical care, economy and society. This consensus establishes the diagnose of adult ADHD based on the 11th edition of International Classification of Diseases (ICD-11), determines the treatment plans based on the etiology and pathogenesis of the disease, recommends psycho-stimulants as the first-line pharmacotherapy for adult ADHD and selective noradrenalin reuptake inhibitors (NARIs) as the second-line pharmacotherapy to reduce the core symptoms, and combines non-pharmacological treatments, such as cognitive behavioral therapy, health education and lifestyle training, aiming to improve patients' functioning and quality of life to the utmost.

Examining Predictors of Depression and Anxiety Symptom Change in Cognitive Behavioral Immersion: Observational Study

Background Depressive and anxiety disorders are the most common mental disorders, and there is a critical need for effective, affordable, and accessible interventions. Cognitive Behavioral Immersion (CBI) is a novel group-based cognitive behavioral skills training program delivered by lay coaches in the metaverse that can be accessed through various modalities including virtual reality (VR) head-mounted displays or flat-screen devices. Combining its ability to offer empirically supported therapy skills in a digital setting that can still facilitate interpersonal variables (eg, working alliance and sense of social support) with the aid of lay coaches, CBI has the potential to help fill this critical need. Objective This study had 2 primary aims. First, we aimed to examine changes in depression and anxiety symptoms in a sample of individuals who participated in CBI. Second, we aimed to examine 2 interpersonal process variables (working alliance and web-based social support) as predictors of symptom changes. We predicted CBI participants would experience depression and anxiety symptom improvements and that such improvements would be associated with an increase in both interpersonal process variables. Methods The study sample consists of 127 participants who endorsed clinical levels of depression or anxiety symptoms during their first CBI session and attended at least 2 sessions. Participants were asked to complete self-report measures of depression symptoms, anxiety symptoms, alliance, and web-based social support throughout their participation in CBI. Results Repeated measures ANOVAs determined that depression and anxiety symptom scores differed significantly across sessions (Ps&lt;.01). We also found participants’ web-based social support predicted improvement in depression symptoms (P=.01), but neither the alliance nor web-based social support predicted change in anxiety symptoms (Ps&gt;.05). We also observed a significant difference in anxiety symptoms between participants who used a VR head-mounted display to access CBI and those who did not, such that participants who used VR head-mounted displays endorsed lower anxiety symptoms than those who did not at nearly every session (P=.04). Conclusions Participation in CBI is associated with both depression and anxiety symptom improvement. Web-based social support may play an important role in fostering changes in depression symptoms. Future studies are encouraged to continue examining the process of change in CBI with special attention paid to methods that can elucidate causal mechanisms of change.

The effect of sustainable low-dose sildenafil and cognitive-behavioral training on sexual function in methadone-treated men–a randomized controlled trial

Background Sexual dysfunction caused by opioids is one of the serious problems of drug misusers. Objective This study aimed to evaluate and compare the effect of continuous low-dose sildenafil treatment alongside psychological training on the sexual function of methadone-treated patients. Method This randomized clinical trial was conducted on methadone-treated men with sexual dysfunction. Patients were randomly divided into two treatment groups: sildenafil 25 mg and psychological training. Sexual Quality of Life-Men, Sexual Self-Efficacy Scale–Erectile, and the International Index of Erectile Function were used before and 4 weeks after the end of the intervention. Results A total of 67 couples were included in the study (34 psychological interventions vs. 33 sildenafil group). After 4 weeks of treatment, the mean of male erectile function (33.73 ± 8.114 and 27.62 ± 6.238, p = 0.003) and sexual self-efficacy score (78.36 ± 12.713 and 69.62 ± 14.940, p < 0.0001) in the sildenafil group were statistically significant compared to the psychological group, however, the sexual quality score of the two groups was not statistically significant (31.48 ± 9.216 and 31.71 ± 11.333, p = 0.342). Conclusions The sexual function of methadone-treated men in both groups was significantly improved, yet this difference was significantly greater in the pharmaceutical treatment group than the trainings. As a result, due to the high need for treatment, any type of intervention (medication or psychotherapy) will be effective in these patients.

Effectiveness of a universal personalized intervention for the prevention of anxiety disorders: Protocol of a randomized controlled trial (the prevANS project)

BackgroundTo date, all preventive anxiety disorders interventions are one-fit-all and none of them are based on individual level and risk profile. The aim of this project is to design, develop and evaluate an online personalized intervention based on a risk algorithm for the universal prevention of anxiety disorders in the general population. MethodsA randomized controlled trial (RCT) with two parallel arms (prevANS vs usual care) and 1-year follow-up including 2000 participants without anxiety disorders from Spain and Portugal will be conducted.The prevANS intervention will be self-guided and can be implemented from the prevANS web or from the participants' Smartphone (through an App). The prevANS intervention will have different intensities depending on the risk level of the population, evaluated from the risk algorithm for anxiety: predictA. Both low and moderate-high risk participants will receive information on their level and profile (risk factors) of anxiety disorders, will have access to stress management tools and psychoeducational information periodically. In addition, participants with a moderate-high risk of anxiety disorders will also have access to cognitive-behavioral training (problem-solving, decision-making, communication skills, and working with thoughts). The control group will not receive any intervention, but they will fill out the same questionnaires as the intervention group.Assessments will be completed at baseline, 6 and 12-month follow-up. The primary outcome is the cumulative incidence of anxiety disorders. Secondary outcomes include depressive and anxiety symptoms, risk probability of anxiety disorders (predictA algorithm) and depression (predictD algorithm), improvement in physical and mental quality of life, and acceptability and satisfaction with the intervention. In addition, cost-effectiveness and cost-utility analyses will also be carried out from two perspectives, societal and health system, and analyses of mediators and moderators will also be performed. DiscussionTo the best of our knowledge, prevANS study will be the first to evaluate the effectiveness and cost-effectiveness of a personalized online intervention based on a risk predictive algorithm for the universal prevention of anxiety disorders.

Obesity and depression: the course of depressive disorders depending on the body mass index, the role of physical activity and cognitive-behavioral therapy for their correction

Purpose: to establish the relationship between the severity of the course of depressive disorders and body mass index in patients with non-alcoholic fatty liver disease on the background of abdominal obesity, the role of physical activity and cognitive-behavioral therapy for their correction.&#x0D;  Materials and methods. 272 people (136 women and 136 men) were examined. The patients were divided into two clinical groups: 1st group – 90 people with non-alcoholic fatty liver disease and overweight (average body mass index =27.5±1.31 kg/m2), who followed only dietary recommendations and a complex physical exercises; 2nd group  - 92 people with non-alcoholic fatty liver disease  and abdominal obesity of the 1st degree (average body mass index =31.74±1.03 kg/m2), who additional  underwent a 6-month course of cognitive-behavioral therapy. The control group consisted of 90 people with normal body weight (average body mass index =22.41±1.43 kg/m2). The Beck scale was used to assess the presence of depression.&#x0D; Results. Depression in patients of the 1st and 2nd groups was registered in 2.3 times (x2=28.105, p=4.762e-10&lt;0.05) and 2.6 times more often (x2=12.019, p=0.007&lt;0.05), than in the control group. Mild depressive disorders in 1.9 times (D=0.304, p=0.032&lt;0.005) more often recorded in young women (up to 45 years old). Patients of the 2nd group, who additionally received a course of CBT, recorded a decrease in the number of depressive disorders of moderate severity by 3.33 times (D=0.1837, p=0.0133), compared to the patients of the 1st group.&#x0D; Conclusions. Gender-age characteristics and weight affect the severity of depressive disorders in obese patients. To reduce the number of depressive disorders and optimize body mass index, it is mandatory to use combined treatment in the form of aerobic exercises and cognitive-behavioral training.

PsicAP transdiagnostic protocol of group cognitive-behavioral training for emotional disorders in Dominican Republic: a randomized controlled trial protocol

Emotional disorders (ED) such as anxiety, depression and somatization are extremely prevalent disorders that can affect an individual’s quality of life and functionality. Primary Health Care (PHC) is the first place to identify most patients with these conditions. Mental health services in the Dominican Republic, as well as in Latin America and the Caribbean in general, are unable to provide appropriate care for most people with mental disorders. Using evidence-based treatment protocols is also crucial to make progress in helping people with ED. The PsicAP project is a group intervention that uses a transdiagnostic approach and is grounded in cognitive-behavioral techniques. The program is implemented in 7 group sessions, each lasting for one and a half hours. The program has been shown to be effective in reducing clinical symptoms, dysfunction, and in improving quality of life. It is also a non-time-intensive, low-cost treatment that is helpful for addressing EDs in a PHC context. The objective is to bring psychological treatments into PHC facilities of Dominican Republic, making them more accessible for a larger amount of the population.

Comparison between Standard Expository Cognitive Behavioral Therapy (CBT-E) and Immersive Virtual Reality CBT (CBT-VR) for Rehabilitation of Patients Affected by Occupational Stress Disorders: Study Protocol.

Work-related stress presents a significant impact on work performance and physical health. It has been associated with the onset of a multitude of symptoms that can lead to occupational stress diseases, namely Adjustment Disorder and Post-Traumatic Stress Disorder. The literature has evidenced that "exposure therapy" of cognitive-behavioral training (CBT-E) seems to be the most effective technique to manage stress symptoms, including work stress diseases, and several studies have considered Virtual Reality (VR) as an adjuvant tool to exposure-based psychotherapy (CBT-VR) for the treatment of multiple psychiatric disorders. The aim of this study is to evaluate the effectiveness of CBT with exposure to stressful work scenarios in imaginative (CBT-E) and in immersive virtual reality (CBT-VR) scenarios in a group of workers affected by work-related stress disorders and compare the clinical and physiological outcomes between the two exposure techniques. A long-term goal would be to develop an evidence-based rehabilitation program as a treatment for the reintegration into work of patients affected by these psychiatric disorders.

Effect of a novel telehealth device for dietary cognitive behavioral intervention in overweight or obesity care

Obesity has become a major public health issue which relate to numerous physical problems and highly comorbid with depression and anxiety. Recently, some studies of technology-based interventions for weight reduction emerged to overcome the barriers from time, cost and distance. Mood component and eating behavior related to obesity are less discussed so far with technology-based intervention though. This pilot study was aimed to investigate the effect of telehealth assisted intervention on weight reduction, mood status, and eating behavior change under a smartphone application (app) with novel 3D food picture recognition and incorporated with cognitive behavioral training programs. Adult aged 30–60 years old with overweight were recruited and randomly assigned to control-first group and intervention-first group. In period 1, control-first group had regular life and intervention-first group underwent app intervention; in period 2, two groups went crossover. Body composition and psychological/behavioral questionnaires were collected at baseline, end of period 1, and end of period 2. Nonparametric statistics was performed for data analyzing. A total of 20 participants were enrolled. In control-first group, there were statistically significant reduction in body weight (− 0.55 kg, p = 0.02) and change of body weight percentage (− 0.6%, p = 0.02) after App use. In intervention-first group, the fat percentage decreased by 0.4% after App use in period 1, and increased by 0.05% in period 2. The integrated crossover data revealed that subjects of App group had significant improvements in mindful eating behavior. This pilot study showed the effectiveness in using CogniNU app for weight control and eating behavior. The difference of short-term and long-term effectiveness of technology-based weight control intervention deserves more investigation in the future.Clinical Trial Registration: ISRCTN16082909.
