Acceptance and Commitment Therapy and Weight-Related Difficulties in Overweight and Obese Adults: A Systematic Review.

Multiple studies have investigated the efficacy of acceptance and commitment therapy (ACT) in improving psychological flexibility among overweight and obese individuals. However, to date, no specific reviews have focused on ACT and weight-related difficulties in this population. This systematic review of the literature aims to identify and assemble all ACT interventions in randomized controlled trials (RCT) that address weight-related difficulties in the treatment of overweight and obese adults. The PRISMA 2020 framework was used for the systematic review, includes manual and computerized database searches. Five databases (Medline, PubMed, Scopus, PsycInfo, and Google) were utilized to gather all articles that: (a) published in English; (b) adopted the RCT design; (c) used ACT as an intervention; (d) included adult participants aged over 18 years with BMI of over 25 kg/m2, and (e) included weight-related difficulties and weight as outcome measures. The review identified seven studies comprising 698 overweight or obese participants of both genders. Improvements were reported in weight-related difficulties and percentage of weight loss in the ACT group and the non-ACT group. The present review supports ACT as an effective intervention that can help adults with weight-related difficulties and excess body weight. Further studies should be conducted in various overweight or obese populations with a more systematic RCT research design to establish the effectiveness of ACT in this area.

Sex differences in PTSD symptoms: A differential item functioning approach.

OBJECTIVE: Evidence has suggested there are sex differences in posttraumatic stress disorder (PTSD) symptom expression; however, few studies have assessed whether these differences are due to measurement invariance. This study aimed to examine sex differences in PTSD symptoms based on the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) using differential item functioning (DIF). METHOD: Confirmatory factor analysis was conducted on the DSM-5 model of PTSD, followed by a multiple indicators multiple causes (MIMIC) model to examine possible DIF using the PTSD Checklist for DSM-5. Data were analyzed from a Malaysian adolescent sample (n = 481) of which 61.7% were female, with a mean age of 17.03 years. RESULTS: The results indicated the presence of DIF for 2 of 20 PTSD criteria. Females scored significantly higher on emotional cue reactivity (B4), and males reported significantly higher rates of reckless or self-destructive behavior (E2) while statistically controlling for the latent variables in the model. However, the magnitude of these item-level differences was small. CONCLUSION: These findings indicate that despite the presence of DIF for 2 DSM-5 symptoms, this does not provide firm support for nonequivalence across sex.

Childhood Maltreatment and Symptoms of PTSD and Depression Among Delinquent Adolescents in Malaysia.

Adolescents in the juvenile justice system are known to suffer from various psychological disorders. Less is known about how childhood psychological trauma is related to psychological disorders among delinquent adolescents in Malaysia. This study investigated the relationship between childhood maltreatment and depressive and Posttraumatic Stress Disorder (PTSD) symptoms. Of 327 adolescents 96% were exposed to at least one childhood victimization. Significant differences were found for all types of victimization (i.e. maltreatment, sexual abuse, severe assault, neglect, and family victimization) between delinquent and non-delinquent adolescents. Females were more likely to be involved in family victimization, while males were more likely to experience severe assault and crime victimization. Delinquent adolescents reported depressive and PTSD symptoms significantly more than non-delinquent adolescents. The prevalence of PTSD and depressive symptoms among delinquents was 20.8 and 52.7% respectively. Highly victimized delinquent adolescents and/or those victimized in family-related events were at significantly higher risk to develop psychiatric symptoms.

Preliminary findings on lifetime trauma prevalence and PTSD symptoms among adolescents in Sarawak Malaysia.

OBJECTIVE: The objective of this study is to determine the prevalence of lifetime exposure to traumatic events and its relation to PTSD symptoms. METHODS: Participants were randomly selected from several schools located in the city of Kuching. There were 85 adolescents participating in this study, with ages ranging from 13 to 14 years old, of whom 31% (n=26) were males and 69% (n=59) females. The Child Posttraumatic Stress Index-Revised, The Harvard Trauma Questionnaire and a lifetime trauma checklist were used in this study. RESULTS: Results showed that 77.6% of participants were exposed to at least one lifetime trauma. The most frequently reported traumas were road accident (20.1%), death of a family member (19.7%), and almost drowning (10%). There was more indirect trauma than direct trauma exposure. Males were more likely to be involved in traumatic events than females. Results showed that 7.1% (6) exhibited PTSD symptoms. There was no significant difference in the mean score of CPTS-RI between genders and among ethnic groups. Total exposure to traumatic events was significantly correlated with PTSD symptoms. CONCLUSION: Findings suggest that number of lifetime traumatic events was quite high and multiple exposures to traumatic events were significantly related to PTSD symptoms.
