The effectiveness of group-based, parent-only weight management interventions for children and the factors associated with outcomes: a systematic review.

BACKGROUND: Obesity in Childhood is a significant public health issue, which requires both a preventative and treatment approach. International guidelines continue to recommend family-focused, multicomponent, childhood weight management programmes and many studies have investigated their effectiveness, however, findings have been mixed and primarily based on weight. Thus, the aim of this review was to assess the effectiveness of group-based parent-only interventions on a broad range of child health-related outcomes and to investigate the factors associated with intervention outcomes. METHODS: An electronic database search was conducted using CINAHL, Medline, PsychINFO, Embase and the Cochrane Database of Systematic Reviews: 522 articles were identified for full text review and 15 studies were selected. The quality of studies were appraised and data were synthesised according to the review aims. RESULTS: Parent-only group interventions are effective in changing children's weight status, as well as other outcomes such as health behaviours and self-esteem, although these were reported inconsistently. Parent-only interventions were generally found to be similar to parent-child interventions, and minimal contact interventions but better than a waiting list control. Factors found to be associated with treatment outcomes, included session attendance, the child's age and weight at baseline, socioeconomic status of families and modification to the home food environment. The methodological quality of the studies included in the review was low, with only six studies rated to be methodologically adequate. CONCLUSIONS: Parent-only interventions may be an effective treatment for improving the health status of children and their families, particularly when compared with waitlist controls. However, results need to be interpreted with caution due to the low quality of the studies and the high rates of non-completion.

What Are the Psychosocial Needs of Adolescents and Young Adults with Cancer? A Systematic Review of the Literature.

Adolescents and young adults with cancer (AYACs) have become recognized as a unique group in recent years. The unique developmental context and related challenges of being a young person with a cancer diagnosis can lead to a distinct and diverse set of psychosocial issues. Existing research has attempted to explore these psychosocial needs and challenges and to develop appropriate and individualized interventions. However, the needs of this group remain unmet, with ongoing calls for individualized support. This systematic review addressed the research question, "what are the psychosocial needs of AYACs aged 15-24 years?." PubMed, PsycINFO, and CINAHL databases were searched to identify relevant studies from January 2000 to December 2022 (inclusive). Qualitative, quantitative, and mixed methods designs were included and 29 studies met inclusion criteria. Findings provide an overview of needs from the existing literature and support the idea of a changing constellation of psychosocial needs for AYACs in areas such as identity, relationships, mental health, autonomy, and occupation. The main implications for theory and future research include the importance of the developmental context and consideration of discrepancies in the age range used within the literature to define this group.

Imagery re-scripting for PTSD: session content and its relation to symptom improvement.

Imagery rescripting (ImRs) is a therapy technique that, unlike traditional re-living techniques, focuses less on exposure and verbal challenging of cognitions and instead encourages patients to directly transform the intrusive imagery to change the depicted course of events in a more desired direction. However, a comprehensive account of how and in what circumstances ImRs brings about therapeutic change is required if treatment is to be optimised, and this is yet to be developed. The present study reports on the development of a coding scheme of ImRs psychotherapy elements identified in the literature as potential ImRs mechanisms. The codes were assessed in relation to short-term outcomes of 27 individuals undergoing ImRs for post-traumatic stress disorder. The timing of the change in the image, degree of activation of the new image and associated cognitive, emotional and physiological processes, self-guided rescripting, rescript believability, narrative coherence and cognitive and emotional shift were identified as being related to symptom change and so are potentially important factors for the re-scripting process.

The role of simulation in imagery rescripting for post-traumatic stress disorder: a single case series.

BACKGROUND: Imagery rescripting (ImRs) is an experiential therapy technique used to change the content and meaning of intrusive imagery in post-traumatic stress disorder (PTSD) by imagining alternative endings to traumatic events. There is growing evidence that ImRs is an effective treatment for PTSD; however, little is known about how it brings about change. AIMS: This study aimed to explore the role of mental simulation as a candidate mechanism of action in ImRs, and, specifically, whether well-simulated imagery rescripts are associated with greater change in symptom severity during ImRs. METHOD: Using a single-case experimental design, seven participants receiving cognitive therapy for PTSD were assessed before, during and after sessions of imagery rescripting for one intrusive image. Participants completed continuous symptom severity measures. Sessions were recorded, then coded for goodness of simulation (GOS) as well as additional factors (e.g. rescript believability, vividness). RESULTS: Participants were divided into high- and low-responders and coding was compared across groups. Correlational analyses were supported by descriptive analysis of individual sessions. High-responders' rescripts tended to be rated as well-simulated compared with those of low-responders. Specific factors (e.g. intensity of thoughts/emotions related to original and new imagery elements, level of cognitive and emotional shift and belief in the resultant rescript) were also associated with reductions in symptom severity. CONCLUSIONS: There was tentative evidence that well-simulated rescripted images tended to be associated with greater reductions in symptom severity of the target image. Clinical implications and avenues for further research are discussed.

Self-compassion, trauma, and posttraumatic stress disorder: A systematic review.

Self-compassion has emerged as an important construct in the mental health literature. Although conceptual links between self-compassion and trauma are apparent, a review has not been completed to examine whether this association is supported by empirical research findings. To systematically summarize knowledge on the association between trauma and/or posttraumatic stress disorder (PTSD) and self-compassion. Searches were conducted in PsycINFO, PubMed, Ovid Medline, Web of Science, Embase, and PILOTS databases, and papers reporting a direct analysis on the relationship between these constructs were identified. The search yielded 35 studies meeting inclusion criteria. Despite considerable heterogeneity in study design, sample, measurement, and trauma type, there was consistent evidence to suggest that increased self-compassion is associated with less PTSD symptomatology and some evidence to suggest that reduced fear of self-compassion is associated with less PTSD symptomatology. There was tentative evidence to suggest that interventions based, in part or whole, on a self-compassion model potentially reduce PTSD symptoms. Although findings are positive for the association between increased self-compassion and reduced PTSD symptoms, the precise mechanism of these protective effects is unknown. Prospective and longitudinal studies would be beneficial in clarifying this. The review also highlighted the variability in what is and should be referred to as trauma exposure, indicating the need for further research to clarify the concept.

Inversion effects in the perception of the moving human form: a comparison of adolescents with autism spectrum disorder and typically developing adolescents.

The "body inversion effect" refers to superior recognition of upright than inverted images of the human body and indicates typical configural processing. Previous research by Reed et al. using static images of the human body shows that people with autism fail to demonstrate this effect. Using a novel task in which adults, adolescents with autism, and typically developing adolescents judged whether walking stick figures-created from biological motion recordings and shown at seven orientations between 0° and 180°-were normal or distorted, this study shows clear effects of stimulus inversion. Reaction times and "inverse efficiency" increased with orientation for normal but not distorted walkers, and sensitivity declined with rotation from upright for all groups. Notably, the effect of stimulus inversion was equally detrimental to both groups of adolescents suggesting intact configural processing of the body in motion in autism spectrum disorder.
