Reaching Young People in Urban and Rural Communities with Mental Health and Wellbeing Support Within a Youth Sports Development Program: Integrating In-Person and Remote Modes of Service Delivery.

Embedding mental health and wellbeing programs within youth sports development programs can help provide more young people with mental health support. However, delivering such programs in multiple locations across metropolitan, regional, and rural areas requires novel solutions to overcome geographic and logistical barriers. We examined the delivery of an integrated system delivered within an Australian junior rugby league program. The program included online assessment and feedback about youth mental health, as well as connection with evidence-informed resources and referral sources via parent telephone and email support. There were four methods of delivering player workshops during training sessions: (a) In-person Delivery Only, (b) In-person + Remote Real-time (video-conferenced), (c) In-person + Remote Prerecorded (video-recorded), and (d) Remote Delivery Only (video-conferenced and/or video-recorded). In-person delivered player workshops were facilitated by local rugby league personnel. Remote delivered workshops were facilitated by psychologists from the mental health research team. Participants were 671 boys (12-15 years; M age = 13.35; SD = 0.35) in 21 metropolitan, regional and rural locations. Regardless of delivery condition, players with elevated anxiety, depression and behavioural problems reported significant declines in symptoms from pre- to post-program, and those within healthy ranges did not change from pre- to post-program. Player workshop enjoyment ratings were higher in the In-person + Remote Real-time condition and the Remote Delivery Only condition than the In-person Delivery Only condition. However, non-completion of the post-program assessment across all conditions was higher than in prior studies and a comparison group of players who did not complete the program was not included. Mental health benefits may be observed across in-person and remote modes of delivering mental health workshops within youth sports programs. However, the involvement of mental health personnel, whether in-person or remotely, and mixed delivery modes, may be important for young people's retention and satisfaction.

Mental health symptoms in children and adolescents during COVID-19 in Australia.

OBJECTIVE: COVID-19 has led to disruptions to the lives of Australian families through social distancing, school closures, a temporary move to home-based online learning, and effective lockdown. Understanding the effects on child and adolescent mental health is important to inform policies to support communities as they continue to face the pandemic and future crises. This paper sought to report on mental health symptoms in Australian children and adolescents during the initial stages of the pandemic (May to November 2020) and to examine their association with child/family characteristics and exposure to the broad COVID-19 environment. METHODS: An online baseline survey was completed by 1327 parents and carers of Australian children aged 4 to 17 years. Parents/carers reported on their child's mental health using five measures, including emotional symptoms, conduct problems, hyperactivity/inattention, anxiety symptoms and depressive symptoms. Child/family characteristics and COVID-related variables were measured. RESULTS: Overall, 30.5%, 26.3% and 9.5% of our sample scored in the high to very high range for emotional symptoms, conduct problems and hyperactivity/inattention, respectively. Similarly, 20.2% and 20.4% of our sample scored in the clinical range for anxiety symptoms and depressive symptoms, respectively. A child's pre-existing mental health diagnosis, neurodevelopmental condition and chronic illness significantly predicted parent-reported child and adolescent mental health symptoms. Parental mental health symptoms, having a close contact with COVID-19 and applying for government financial assistance during COVID-19, were significantly associated with child and adolescent mental health symptoms. CONCLUSION: Our findings show that Australian children and adolescents experienced considerable levels of mental health symptoms during the initial phase of COVID-19. This highlights the need for targeted and effective support for affected youth, particularly for those with pre-existing vulnerabilities.

Helping Clinicians Conceptualise Behavioural Insomnia in Children: Development of the Manifestations and Vulnerabilities of Behavioural Insomnia in Childhood Scale (MAVBICS).

This paper outlines the development and psychometric evaluation of the Manifestations and Vulnerabilities of Behavioural Insomnia in Childhood Scale (MAVBICS), an instrument intended to assess the manifestations of, and factors underpinning, child behavioural insomnia. The MAVBICS comprises two sections: a more general sleep and bedtime information section (Section 1), and a psychometric measure of six theoretically derived factors that underlie, contribute to, and are manifestations of, child sleep problems (Section 2), that is the focus of this research. Study 1 comprised an exploratory factor analysis of Section 2 items (EFA; n = 328 parents of children aged 3-12 years), with a final 25 items found to load highly onto 6 factors; Sleep Maintenance Problems (4 items, α = 0.88), Co-Sleeping Behaviours (4 items, α = 0.93), Bedtime Routines (5 items, α = 0.82), Bedtime Resistance (5 items, α = 0.88), Bedtime Worries (3 items, α = 0.85) and Bedtime Fears (4 items, α = 0.86). Study 2 comprised a confirmatory factor analysis (CFA) of Section 2 items and tests of convergent validity (n = 313), with results confirming the factor structure and providing evidence for convergent validity through correlations in expected directions between MAVBICS scores and other sleep, anxiety and behaviour measures. Study 3 tested the test-retest reliability of Section 2 items (n = 53), and found support for the temporal stability of the MAVBICS over a 2-week period. Overall, the results provide strong preliminary evidence for the validity of the MAVBICS total score and its subscales, although the Bedtime Routines subscale may be less useful.

Feasibility of an Intensive, Disorder-Specific, Group-Based Cognitive Behavioural Therapy Intervention for Adolescents with Social Anxiety Disorder.

This study examined the preliminary acceptability and efficacy of an intensive, group-based, disorder-specific cognitive behavioural therapy (CBT) intervention for adolescents with social anxiety disorder (SAD). Fourteen Australian adolescents with SAD (78.6% female, M age = 13.93 years) and their parents completed the program plus measures of treatment satisfaction, and provided feedback. Clinical interviews and surveys were administered pre-treatment, post-treatment, and at 6-month follow-up to determine diagnostic status and assess related variables. Post-treatment satisfaction scores were very high for adolescents and parents. Post-treatment, 32.3% of participants no longer met criteria for SAD diagnosis, increasing to 42.9% at follow-up. Participants showed sizeable reductions in comorbid diagnoses, significant improvements in global functioning, social anxiety symptoms, and internalising symptoms from pre- to post-treatment (maintained at follow-up), and significant improvements in social skills and social competence from pre-treatment to follow-up. This study supports the use of an intensive CBT program for adolescents with SAD.

Short Research Article: Changes in life functioning in a self-help, online program for child and adolescent anxiety.

BACKGROUND: Anxiety-related functional impairment, as reflected by life interference, is a lesser explored but highly relevant treatment outcome, and it is crucial that it be included and examined in the evaluation of treatment outcomes of internet-delivered Cognitive Behavioural Therapy (iCBT). METHODS: This single group, pre-post study examined changes in life interference and anxiety symptoms in a sample of children (n = 1198; mean age 9.66 years) and adolescents (n = 721; mean age 13.66 years) participating in the BRAVE Self-Help program in Australia. RESULTS: Results demonstrated that both children and adolescents showed improvements in anxiety symptoms, with effect sizes ranging from ηp 2  = .194-.318. Reductions in life interference were evident for children (ηp 2  = .008-.044), particularly later in the programme, but adolescents did not show such effects. Adolescents in the low completer group (completing 3-5 sessions) showed increases in at-home interference (ηp 2  = .038). CONCLUSIONS: Adolescents in particular may require more sessions before entrenched life interference, such as that resulting from avoidance behaviours, can be overcome.

Examining the Process of Implementing a Three-Step Mental Health and Wellbeing System of Care for Children and Adolescents Across Multiple Community Settings.

Mental health problems affect large numbers of young people. Integrated systems are required that can be applied in diverse settings to reach youth 'where they are'. We evaluated the process of implementing a three-step youth mental health and wellbeing system in diverse community settings according to three implementation outcomes: feasibility, penetration and acceptability. The study describes 49 applications of the 'Life-Fit-Learning system' designed to assess the mental health and wellbeing of youth (Assess step), provide feedback on assessment results (Reflect step), and connect them to resources and services proportionate to their needs (Connect step). Within a participatory research approach, 3798 administrations were conducted with youth between 9 and 18 years and 90 administrations were conducted with adults. Implementation was based on the four phases of the Quality Implementation Framework and was staged to integrate stakeholder and consumer feedback and experience gained from focus groups and two pilot phases before full implementation. Feasibility ratings of successful implementation ranged from 86.7 to 96.4% across applications and settings. High penetration rates were achieved. The Life-Fit-Learning system successfully reached 91.9% to 96% of youth with the Assess and Reflect steps and low intensity Connect step resources. Of those, 14.7% to 23% were identified at-risk for mental health problems and 93% to 97% of those at-risk youth additionally received Connect step co-delivered group-based programs (moderate intensity care) and/or individual treatment (high intensity care). Youth and parents reported high satisfaction across all steps and delivery modes. With strong collaboration, an integrated model of care can be delivered feasibly, effectively and satisfactorily to reach large numbers of young people across settings.

Tackling Mental Health in Youth Sporting Programs: A Pilot Study of a Holistic Program.

Linking mental health services to organised sport offers an avenue to identify and improve mental health among adolescents. In this study, we investigated the efficacy, acceptability and feasibility of an integrated mental health system embedded within a junior sports development program. A three-step integrated mental health program for 12- to 15-year-old rugby league players (N = 74) was delivered in urban (n = 44) and rural (n = 33) areas. Specifically, this system (a) assessed participant mental health on primary outcome measures of anxiety, depression, and anger/conduct problems (and secondary outcome measures of personal attributes and relationships), (b) provided feedback to participants, parents and program coordinators, and (c) connected participants and parents to a multi-component intervention including online resources, a group-based workshop program (4 × 30-min sessions), and tailored individual-level follow-up and referral to further care for participants at high risk of mental health problems. From pre- to post-program, boys' anxiety symptoms declined significantly (with only a trend-level reduction in depression), and there were significant improvements in grit (for urban boys only), efficacy to manage negative emotions, and prosocial behaviour. In addition, when boys reported symptoms associated with high risk for mental health problems, providing parents with feedback enhanced boys' access to care and was associated with significant declines in anxiety symptoms. The program was generally acceptable and feasible, with very high retention in the youth sports development program. Overall, early findings support further deployment and evaluation of integrated mental health systems embedded within sporting contexts to address mental health problems among adolescent boys.

Internet-delivered cognitive behavior therapy with minimal therapist support for anxious children and adolescents: predictors of response.

BACKGROUND: In general, Internet-delivered cognitive behavior therapy (iCBT) produces significant reductions in child and adolescent anxiety, but a proportion of participants continue to show clinical levels of anxiety after treatment. It is important to identify demographic, clinical, and family factors that predict who is most likely to benefit from iCBT in order to better tailor treatment to individual needs. METHODS: Participants were 175 young people (7-18 years) with an anxiety disorder, and at least one of their parents, who completed an iCBT intervention with minimal therapist support. Multilevel modeling (MLM) examined predictors of response to iCBT as measured by the slope for changes in the primary outcome measures of child- and parent-reported anxiety scores, from pretreatment, to 12-weeks, 6-month, and 12-month follow-ups, controlling for pretreatment total clinician severity ratings of all anxiety diagnoses. RESULTS: Child age, gender, father age, parental education, parental mental health, parenting style, and family adaptability and cohesion did not significantly predict changes in anxiety in the multivariate analyses. For child-reported anxiety, greater reductions were predicted by a separation anxiety disorder diagnosis (SEP) and elevated depression, with lower reductions predicted by poor couple relationship quality. For parent-reported child anxiety, greater reductions were predicted by higher pretreatment total CSRs, SEP, and lower family income, with lower reductions for children of older mothers. Irrespective of these predictors of change, children in general showed reductions in anxiety to within the normal range. CONCLUSIONS: Overall, children responded well to iCBT irrespective of the demographic, clinical, and family factors examined here. Poor couple relationship quality and older mother age were risk factors for less positive response to iCBT in terms of reductions in anxiety symptoms although still to within the normal range.

Is thin in everywhere?: A cross-cultural comparison of a subsection of Tripartite Influence Model in Australia and Malaysia.

Despite growing research investigating prevalence rates of BD among Malaysian women, there has been limited research conducted in Malaysia with respect to factors contributing to its development and consequences. This study tested a subsection of the Tripartite Influence Model, investigating whether sociocultural influences (family, peers, media) lead to thin ideal internalization, which in turn lead to body dissatisfaction (BD) and subsequently restrained eating and bulimic behaviours in both Australian and Malaysian women. Participants were 421 Australian and 399 Malaysian female emerging adults aged between 18 and 25 years, (M = 20.76; SD = 2.86) who completed questionnaires assessing sociocultural influences, thin ideal internalization, body dissatisfaction, restrained eating and bulimic behaviours. The model, largely supported in both cultures, had two points of difference. For Malaysian but not Australian women, family influence was significantly linked with internalization of the thin ideal. Although BD was significantly linked with restrained eating as predicted for Australian women (albeit rather weakly), it was not significantly linked with restrained eating for Malaysian women. The striking similarity of results across both cultures, suggests that Western body ideals, with their corresponding negative sequelae, have infiltrated the collectivist and developing nation of Malaysia.

Ambulatory Assessment of Adolescent Coping: It's a Complicated Process.

Scholars have long-called for researchers to treat coping as a process that is measured over an arc of time. Ambulatory assessment (AA) offers an appealing tool for capturing the dynamic process of adolescent coping. However, challenges in capturing the coping process are not altogether circumvented with AA designs. We conducted a scoping review of the AA literature on adolescent coping and draw from 60 studies to provide an overview of the field. We provide critiques of different AA approaches and highlight benefits and costs associated with various types of measurement within AA. We also speak to considerations of participant burden and compliance. We conclude with recommendations for developmental scholars seeking to deploy AA to capture this quintessential process among adolescents.

Behavioral Sleep-Related Problems in Clinically Anxious Children: A Parent-Report Diary Study.

Anxiety disorders and behavioral sleep-related problems (SRPs) frequently co-occur during childhood. However, few studies have used the recommended method of a sleep-diary. The present study examined parental perceptions of behavioral SRPs in anxious compared to non-anxious children using a sleep-diary. Parents of 22 clinically anxious children and 29 healthy controls (aged 6-13 years) completed a 7-day sleep-diary of their child's behavioral SRPs. Compared to non-anxious peers, anxious children were rated by parents as more often (a) having a negative mood before bed, (b) delaying bed, (c) requiring parental assistance during the night, especially on weeknights, (d) having difficulty waking on their own the next morning, (e) falling back to sleep after morning waking, and (f) waking in a negative mood. There were no significant group differences in sleep onset latency or sleep duration, and behavioral SRPs of anxious children did not negatively affect their functioning or that of their parents the next day based on parent report. Parents of anxious children are more likely to perceive their children as engaging in behavioral SRPs compared to parents of non-anxious children.

Large-Scale Dissemination of Internet-Based Cognitive Behavioral Therapy for Youth Anxiety: Feasibility and Acceptability Study.

BACKGROUND: Internet-based cognitive behavioral therapy (iCBT) for child and adolescent anxiety has demonstrated efficacy in randomized controlled trials, but it has not yet been examined when disseminated as a public health intervention. If effective, iCBT programs could be a promising first-step, low-intensity intervention that can be easily accessed by young people. OBJECTIVE: The objective of our study was to examine the feasibility and acceptability of a publicly available online, self-help iCBT program (BRAVE Self-Help) through exploration of program adherence, satisfaction, and changes in anxiety. METHODS: This study was an open trial involving the analysis of data collected from 4425 children and adolescents aged 7-17 years who presented with elevated anxiety at registration (baseline) for the iCBT program that was delivered through an open-access portal with no professional support. We assessed the program satisfaction via a satisfaction scale and measured adherence via the number of completed sessions. In addition, anxiety severity was assessed via scores on the Children's Anxiety Scale, 8-item (CAS-8) at four time points: baseline, Session 4, Session 7, and Session 10. RESULTS: Participants reported moderate satisfaction with the program and 30% completed three or more sessions. Statistically significant reductions in anxiety were evident across all time points for both children and adolescents. For users who completed six or more sessions, there was an average 4-point improvement in CAS-8 scores (Cohen d=0.87, children; Cohen d=0.81, adolescents), indicating a moderate to large effect size. Among participants who completed nine sessions, 57.7% (94/163) achieved recovery into nonelevated levels of anxiety and 54.6% (89/163) achieved statistically reliable reductions in anxiety. CONCLUSIONS: Participant feedback was positive, and the program was acceptable to most young people. Furthermore, significant and meaningful reductions in anxiety symptoms were achieved by many children and adolescents participating in this completely open-access and self-directed iCBT program. Our results suggest that online self-help CBT may offer a feasible and acceptable first step for service delivery to children and adolescents with anxiety.

Does an Online CBT Program for Anxiety Impact Upon Sleep Problems in Anxious Youth?

This study aimed to assess whether the transdiagnostic therapy elements of an online cognitive behaviour therapy anxiety program also impact on sleep-related problems (SRPs) in anxious youth. Participants were drawn from two previously published studies evaluating online cognitive behaviour therapy for child anxiety (BRAVE-ONLINE). The study included 63 children 7-12 years of age (M = 9.49, SD = 1.37) and 71 adolescents 12-18 years of age (M = 13.90, SD = 1.68). SRPs, severity of anxiety diagnosis, anxiety symptoms, number of diagnoses, depressive symptoms, and global functioning were assessed at pre-, post-, and 6-month follow-up assessment points. SRPs were positively related to anxiety symptoms and severity for children and were positively related to depression for adolescents. SRPs did not differ between male and female participants, between children and adolescents, or between those who had generalised anxiety disorder in their profile and those who did not. Finally, children but not adolescents participating in the online program demonstrated a significantly greater reduction in SRPs from pre- to posttreatment compared to the waitlist group, and these gains were maintained at 6-month follow-up. Treatment focusing on child anxiety alone may reduce SRPs in children but not adolescents. Although further research is clearly needed, clinicians should ensure that they assess for SRPs in their teenage clients and directly target SRPs in treatment where required.

What's the Worry with Social Anxiety? Comparing Cognitive Processes in Children with Generalized Anxiety Disorder and Social Anxiety Disorder.

Social anxiety disorder (SAD) in children is often comorbid with generalized anxiety disorder (GAD). We investigated whether worry, intolerance of uncertainty, beliefs about worry, negative problem orientation and cognitive avoidance, that are typically associated with GAD, are present in children with SAD. Participants included 60 children (8-12 years), matched on age and gender. Groups included children: with primary GAD and without SAD (GAD); with primary SAD and without GAD (SAD); and without an anxiety disorder (NAD). GAD and SAD groups scored significantly higher than the NAD group on worry, intolerance of uncertainty, negative beliefs about worry and negative problem orientation, however, they did not score differently from each other. Only the GAD group scored significantly higher than the NAD group on cognitive avoidance. These findings further understanding of the structure of SAD and suggest that the high comorbidity between SAD and GAD may be due to similar underlying processes within the disorders.

Can we improve parent attitudes and intentions to access computer-based therapies for their children and adolescents?

BACKGROUND: As gatekeepers, parents can improve the uptake of mental health services among youth. This article asked whether providing parents with a presentation on computer-based therapies is a feasible strategy to improve their knowledge, attitudes and uptake intentions. METHOD: Parents completed a survey before, and immediately after, viewing a presentation on computer-based therapies or an active control. RESULTS: Parents who viewed the computer-based presentation reported significantly greater improvements in knowledge, perceived helpfulness, perceived benefits and intentions to access computer-based therapies; and a significantly greater reduction in perceived problems, compared to active controls. CONCLUSIONS: Information- and demonstration-based presentations are a feasible method for improving attitudes towards computer-based therapies for youth among parents in the community.

Improvements in Interpersonal Functioning Following Interpersonal Psychotherapy (IPT) with Adolescents and their Association with Change in Depression.

BACKGROUND: This study adds to the body of evidence regarding the theoretical underpinnings of interpersonal psychotherapy and the mechanisms through which it impacts upon depression in adolescents. AIMS: The aims were to determine whether the interpersonal constructs proposed to underpin interpersonal psychotherapy do indeed change in response to this therapy and whether such changes are associated with changes in depression in young people. METHOD: Thirty-nine adolescents, aged 13-19 years, with a primary diagnosis of major depressive disorder, were randomly assigned in blocks to group or individual treatment. Assessments were conducted at pre and posttreatment, and 12-month follow-up. RESULTS: The results supported the hypotheses, with significant improvements in social skills, social functioning, and the quality of parent-adolescent relationships, and an increase in secure attachment style and decrease in insecure attachment style being evident following treatment. Benefits were maintained at 12-month follow-up. Adolescents who showed greater reductions in depressive symptoms over this period tended to also show greater improvement in parent reported social skills, quality of the parent-adolescent relationship, and attachment style from pretreatment to 12-month follow-up. CONCLUSIONS: The findings are consistent with the proposed underpinnings of interpersonal psychotherapy. Adolescents showed significant improvements in interpersonal functioning and changes in attachment style following treatment, and changes in social skills, parent-adolescent conflict and attachment style were associated with reductions in depression. As such, the results add to the body of knowledge regarding the construct validity of interpersonal psychotherapy as an intervention for depression in young people. Clinical implications and directions for future research are discussed.

Group versus individual interpersonal psychotherapy for depressed adolescents.

BACKGROUND: This study adds to the limited evidence concerning the benefits of Interpersonal Psychotherapy (IPT) with depressed adolescents. It evaluates the long-term effects of group versus individual delivery of this treatment approach. AIMS: To conduct a small-scale examination of the long-term efficacy of group versus individual delivery of IPT for depressed adolescents. METHOD: Thirty-nine adolescents, aged 13-19 years, with a primary diagnosis of Major Depressive Disorder, were randomly assigned in blocks to either group or individual delivery of IPT. Standardized clinical interview and questionnaire assessments were conducted at pre- and posttreatment, and 12-month follow-up. RESULTS: Intent-to-treat (ITT) analyses indicated significant improvements in depression, anxiety, youth-reported internalizing problems, and global functioning from pre- to posttreatment for those receiving IPT, with no significant differences in outcome between group and individual formats of delivery. Improvements were maintained at 12-month follow-up. Completer analyses also revealed significant and sustained improvements on these measures for those receiving IPT, with no differences in outcome between therapy formats for most measures. Individual IPT showed significantly greater improvements than group IPT in parent-reported internalizing problems for the completer but not the ITT analyses. CONCLUSIONS: Both individual and group formats of IPT offer promise in producing long-term benefits in the treatment of depression among adolescents.

The appearance culture between friends and adolescent appearance-based rejection sensitivity.

Appearance-based rejection sensitivity (appearance-RS) is the tendency to anxiously expect, readily perceive, and overreact to signs of rejection based on one's appearance, and is associated with a number of psychological and social problems (Park, 2007). This study of 380 adolescents (Mage = 13.84) examined a model linking the appearance culture between friends with appearance-RS in adolescent boys and girls, via internalisation of appearance ideals, social comparison, and body dissatisfaction. Gender differences were also tested. Consistent with expectations, appearance-focused characteristics of the friendship context were associated with heightened appearance-RS via internalization of appearance ideals, social comparison, and body dissatisfaction. The appearance-focused friend characteristics that were associated with appearance-RS included exposure to friends' appearance conversations, appearance teasing that caused distress, and perceived pressure to be attractive. Notably, associations rarely differed for boys and girls, with one exception: the association between BMI and body dissatisfaction was stronger in girls than in boys.

Interpersonal factors associated with depression in adolescents: are these consistent with theories underpinning interpersonal psychotherapy?

The aim of this study was to investigate whether depressed adolescents differed from non-depressed adolescents in terms of constructs consistent with those that are proposed to underpin interpersonal psychotherapy. In particular, it was hypothesized that compared with non-depressed adolescents, depressed adolescents would demonstrate a greater number of negative life events associated with interpersonal loss and major life transitions, a more insecure attachment style and poorer communication skills, interpersonal relationships and social support. Thirty-one clinically diagnosed depressed adolescents were matched with 31 non-depressed adolescents on age, gender and socio-economic status. The 62 participants were aged between 12 and 19 years and comprised 18 male and 44 female adolescents. On a self-report questionnaire, depressed adolescents reported a greater number of negative interpersonal life events, a less secure attachment style and scored higher on all insecure attachment styles compared with the non-depressed adolescents. In addition, depressed adolescents demonstrated lower levels of social skill (on both adolescent and parent report), a poorer quality of relationship with parents (on both adolescent and parent report) and lower social competence (adolescent report only). Parents of depressed adolescents also reported more negative parental attitudes and behaviours towards their adolescent compared with parents of non-depressed adolescents. Thus, the results of this study are consistent with the constructs underlying interpersonal psychotherapy and suggest their usefulness in the assessment, conceptualization and treatment of adolescent depression. Clinical implications are discussed.

Motivational processes contributing to disturbances in women's body image and eating.

Reinforcement Sensitivity Theory (RST) provides a neurobiological personality framework for understanding approach and avoidance behavioural patterns. Recent research suggests an association between RST personality traits (reward interest and behavioural inhibition system [BIS]) and women's body image and eating behaviours. The current study aimed to extend this research by testing for indirect relationships between reward interest and BIS and eating disorder symptoms, as mediated through thin ideal internalisation. Adult female participants (N = 354, M = 22.06 years of age, SD = 6.78) completed self-report measures of reward interest, BIS, thin ideal internalisation, and eating disorder symptoms (i.e., restraint, eating concerns, weight and shape concerns). Indirect relationships were tested using bootstrapped mediation analyses. Results showed thin ideal internalisation mediated the pathways between the BIS and restraint, eating concern, and weight and shape concerns. Reward interest was not associated with thin ideal internalisation, or with eating disorder symptoms. Although the application of RST to women's body image is an emerging research area, these novel findings suggest BIS trait sensitivity may increase women's risk of body image concerns and restricted eating, via increased levels of thin ideal internalisation. Overall, these findings provide preliminary support for inclusion of individual differences in BIS sensitivity in risk factor models of body image and eating disturbances. Future research should aim to replicate these findings in more diverse samples, using longitudinal designs.
