Smoking Cessation Interventions and Abstinence Outcomes for People Living in Rural, Regional, and Remote Areas of Three High-Income Countries: A Systematic Review.

INTRODUCTION: Tobacco smoking rates in high-income countries are greater in rural, regional, and remote (RRR) areas compared to cities. Yet, there is limited knowledge about interventions targeted to RRR smokers. This review describes the effectiveness of smoking cessation interventions for RRR smokers in supporting smoking abstinence. AIMS AND METHODS: Seven academic databases were searched (inception-June 2022) for smoking cessation intervention studies to include if they reported on RRR residents of Australia, Canada, or the United States, and short- (<6 months) or long-term (≥6 months) smoking abstinence outcomes. Two researchers assessed study quality, and narratively summarized findings. RESULTS: Included studies (n = 26) were primarily randomized control (12) or pre-post (7) designs, from the United States (16) or Australia (8). Five systems change interventions were included. Interventions included cessation education or brief advice, and few included nicotine monotherapies, cessation counseling, motivational interviewing, or cognitive behavioral therapy. Interventions had limited short-term effects on RRR smoking abstinence, decreasing markedly beyond 6 months. Short-term abstinence was best supported by contingency, incentive, and online cessation interventions, and long-term abstinence by pharmacotherapy. CONCLUSIONS: Cessation interventions for RRR smokers should include pharmacotherapy and psychological cessation counseling to establish short-term abstinence, and identify effective means of maintaining abstinence beyond 6 months. Contingency designs are a suitable vehicle for psychological and pharmacotherapy support for RRR people who smoke, and intervention tailoring should be explicitly considered. IMPLICATIONS: Smoking disproportionately harms RRR residents, who can encounter access barriers to smoking cessation support. High-quality intervention evidence and outcome standardization are still required to support long-term RRR smoking abstinence.

SMART recovery for youth: a small, exploratory qualitative study examining the potential of a mutual-aid, peer support addictive behaviour change program for young people.

BACKGROUND: SMART (Self-Management and Recovery Training) Recovery is a mutual-aid program informed by cognitive behaviour therapy and motivational interviewing that provides support for a range of addictive behaviours. SMART Recovery has not been adapted to target young people with addictive behaviours despite the potential to overcome important barriers affecting youth engagement in other addiction programs. This study aimed to engage young people and SMART Recovery facilitators in qualitative interviews and focus groups to explore the potential of such a program and gain specific insights for its development. METHODS: We conducted qualitative interviews and a focus group with five young people (aged between 14 and 24 years) and eight key stakeholders (including seven SMART Recovery facilitators) to obtain recommendations on how best to reach, engage, and support young people with addictive behaviours in a tailored SMART Recovery program. Qualitative data was transcribed and analysed using iterative categorization. RESULTS: Five key themes were identified when developing and delivering youth-targeted SMART Recovery. [1] 'Discussing personal experiences to promote a shared identity' refers to the benefits of creating a forum where personal stories are used to connect with others and validate one's experiences. [2] 'Flexible and patient approach' emphasises a preference for facilitators to take a more gentle, less direct approach that allows for discussion beyond addictive behaviours. [3] 'Balancing information and skills with the space for discussion' acknowledges that youth want to connect in a variety of ways, beyond discussion of addictive behaviours, and that they wish to lead skill sharing and development. [4] 'Conveying a community for youth through language' highlighted the need to focus on connecting youth and to avoid the use of generic language to engage young people. [5] 'Group logistics and competing demands' refers to the logistical considerations of implementing a group program for youth that takes into account their competing demands and group accessibility. CONCLUSION: The findings point to considerations for developing youth specific mutual-aid groups, in particular a youth-targeted SMART Recovery program, such as by ensuring the conversation is youth-led and with an informal and flexible approach to guide group discussion.

Adapted motivational interviewing for brief healthcare consultations: A systematic review and meta-analysis of treatment fidelity in real-world evaluations of behaviour change counselling.

BACKGROUND: Behaviour change counselling (BCC) is an adaptation of motivational interviewing (MI) designed to maximize the effectiveness of time-limited health behaviour change consultations. To improve intervention quality and understanding of treatment effects, it is recommended that evaluations of health behaviour change interventions incorporate existing fidelity frameworks (e.g. The National Institutes of Health [NIH] Behaviour Change Consortium) and ensure that treatment fidelity is assessed and reported. PURPOSE: This systematic review was designed to examine (a) adherence to NIH fidelity recommendations, (b) provider fidelity to BCC and (c) impact of these variables on the real-world effectiveness of BCC for adult health behaviours and outcomes. METHODS AND RESULTS: Searches of 10 electronic databases yielded 110 eligible publications describing 58 unique studies examining BCC delivered within real-world healthcare settings by existing providers. Mean study adherence to NIH fidelity recommendations was 63.31% (Range 26.83%-96.23%). Pooled effect size (Hedges g) for short-term and long-term outcomes was .19 (95% CI [.11, .27]) and .09 (95% CI [.04, .13]), respectively. In separate, random-effects meta-regressions, neither short-term nor long-term effect sizes were significantly modified by adherence to NIH fidelity recommendations. For the subgroup of short-term alcohol studies (n = 10), a significant inverse relationship was detected (Coefficient = -.0114, 95% CI [-.0187, -.0041], p = .0021). Inadequate and inconsistent reporting within the included studies precluded planned meta-regression between provider fidelity and BCC effect size. CONCLUSIONS: Further evidence is needed to clarify whether adherence to fidelity recommendations modifies intervention effects. Efforts to promote transparent consideration, evaluation and reporting of fidelity are urgently needed. Research and clinical implications are discussed.

A pilot randomised controlled trial of abrupt versus gradual smoking cessation in combination with vaporised nicotine products for people receiving alcohol and other drug treatment.

BACKGROUND: Vaporised nicotine products (VNPs) may be a potential quit smoking strategy. Most research has permitted participants to use VNPs ad libitum. This is the first study to examine combining the use of a VNP with a gradual or abrupt cessation guideline. This study aims to test the potential feasibility of a quit smoking strategy (abrupt verses gradual cessation) in combination with vaporised nicotine products among people in AOD treatment. METHODS: We conducted a pilot randomised controlled trial between April 2018 and July 2019. Participants were recruited from AOD programs located within one area health service in Australia. Participants were provided with two VNPs, a 12-week supply of nicotine e-liquid and randomised to either the abrupt (assigned a quit date the day they were provided their VNP) or gradual quit smoking strategy (reduce baseline number of cigarettes per day by 25% over a 4 week period), no further behavioral support was provided. Feasibility was assessed through successful recruitment rates, retention, and adherence to study conditions. Participant perceived helpfulness and satisfaction assessed acceptability. RESULTS: Among 80 interested individuals, 66 were eligible and consented (100% recruitment rate). From the 66 participants that consented and completed the baseline survey, 60 received the intervention assigned at a 1:1 ratio with 30 in the gradual cessation and 30 in the abrupt cessation group. Retention was 86.4% (n = 52) at 12-weeks post-intervention commencement. Ninety-six percent (n = 25) of participants in the gradual and 95.8% (n = 23) of participants in the abrupt group were using the VNPs at 12-weeks (p = 0.66). There was no difference in adherence to the assigned quit plan between gradual cessation 44% (n = 11) and abrupt cessation 71% (n = 17) groups (p = 0.117). Median perceived helpfulness of VNPs was high for both gradual (10/10) and abrupt (9/10) groups (p = 0.813). Similarly, median perceived satisfaction of VNPs was high for both gradual (9 /10) and abrupt (8/10) groups (p = 0.414). CONCLUSIONS: AOD participants found an intervention that involved VNPs to be satisfying and helpful. Future large scale trials are needed to elucidate whether a gradual or abrupt cessation guideline is more beneficial in main a quit attempt with a VNP.

Addressing smoking in sheltered homelessness with intensive smoking treatment (ASSIST project): A pilot feasibility study of varenicline, combination nicotine replacement therapy and motivational interviewing.

BACKGROUND: This pilot study aimed to test the feasibility of providing varenicline in combination with nicotine replacement therapy (NRT) and motivational interviewing (MI) to adult male smokers attending a clinic in a hostel for homeless people. METHODS: A single group pre- and post-treatment (12 weeks following intervention commencement) design with embedded process evaluation (at weekly counselling and fortnightly safety check-ins). Participants were 20 male smokers attending a health clinic within a homelessness service in Sydney, Australia, between December 2019 and March 2020. Participants set a target quit date 7-days post intervention commencement. Adverse events, self-reported abstinence, cigarettes per day, treatment adherence and acceptability of the study interventions were assessed 12 weeks post intervention commencement. Abstinence was biochemically verified. Results are complete cases. RESULTS: Retention was 65% at 12-weeks post-intervention commencement (n = 13). No related adverse events were reported. Three participants (15%) reported continuous abstinence. Two participants self-reported 30-day point prevalence abstinence (10%), confirmed by CO level. Participants who did not quit smoking (n = 10), reported a significant reduction in the number of cigarettes smoked per day (19.4 vs 4.7, p < .01). Cravings, withdrawal symptoms, and psychological distress significantly decreased from baseline to 12-week follow-up (all < 0.01). Adherence to the pharmacological interventions was good, most used combination NRT and varenicline. Adherence to the counselling sessions was low, attending three of 12 sessions. Both NRT and MI were rated as highly acceptable. Some participants expressed concerns about the safety of varenicline. CONCLUSIONS: The intervention was feasible and acceptable and associated with short-term smoking cessation and significant reductions in the number of cigarettes smoked-per-day.

Barriers and facilitators to using vaporised nicotine products as smoking cessation aids among people receiving treatment for substance use disorder.

INTRODUCTION: Vaporised nicotine products (VNPs) may be useful smoking cessation aids for people in alcohol and other drug (AOD) treatment, a population with high tobacco-related morbidity and mortality rates. This qualitative study aimed to examine the barriers and facilitators of using VNPs as part of a clinical trial to reduce or quit smoking among people in AOD treatment. METHODS: Thirteen people in AOD treatment who were participating in a trial of VNPs for smoking cessation (QuitENDs) completed a brief semi-structured interview examining experiences of using VNPs to reduce or quit smoking. Transcribed data was analysed using the iterative categorisation framework. RESULTS: Many participants expressed the benefit of having a smoking cessation aid that addressed nicotine cravings and the behavioural hand-to-mouth action to help them reduce or quit smoking. Although many participants reported that VNPs were easy to use, some found maintaining the device to be challenging. Some participants described Australian regulations limiting use of VNPs as reducing their desire to use the device as a cessation aid. Many participants attempting to reduce or quit tobacco and cannabis simultaneously stated that VNPs alone were insufficient to help them reduce or quit tobacco. CONCLUSIONS: VNPs hold significant promise as smoking cessation aids among people in AOD treatment because of their unique ability to satisfy both nicotine cravings and behavioural habits. However, multiple barriers, such as accessibility, maintenance, and the challenges of reducing other substance use simultaneously also need to be addressed for optimal engagement in clinical trials with VNPs to quit smoking.

School and educational support programmes for paediatric oncology patients and survivors: A systematic review of evidence and recommendations for future research and practice.

OBJECTIVES: The Psychosocial Standards of Care (PSSC) in paediatric oncology prescribe the minimum standards for education support. It is unknown, however, if published education support programmes for children with cancer meet the PSSC standards for education support. Successful implementation of standards for education support is challenging but may be achieved with guidance. We aimed to (1) review education support programmes for childhood cancer patients and survivors against the PSSC standards and (2) provide practical recommendations for future research and implementation of education support programmes. METHODS: We searched PsycINFO, PubMed, CINAHL, EMBASE, and Educational Resources Information and Center databases. We reviewed the education support programmes using five evaluation criteria derived from the PSSC and summarised the structure of identified programmes. We examined the features and limitations of programmes that met all evaluation criteria. RESULTS: We identified 20 education support programmes in paediatric oncology, including peer programmes (n = 3), teacher programmes (n = 5), and school re-entry programmes (SRPs n = 12). We found that three SRPs met all evaluation criteria and that SRP components were timed according to the child's position on the cancer trajectory (e.g., diagnosis and treatment, school re-entry, and follow up throughout schooling). The supporting evidence of the programmes, however, is unclear due to the lack of adequately designed studies. CONCLUSIONS: SRPs provide a promising structure for future education support programmes. We recommend strategies for developing and evaluating education support that adheres to the PSSC and adapts to international and local contexts.

Smoking cessation interventions for people living in rural and remote areas: a systematic review protocol.

INTRODUCTION: Smoking rates among people living in rural and remote areas are higher and quit rates are lower over the past 10 years compared with people living in suburban and urban areas. Higher smoking rates contribute to greater tobacco-related disease and morbidity in rural and remote areas. Physical and social isolation, greater exposure to pro-tobacco marketing, pro-tobacco social norms, and lower socioeconomic and educational levels are contributing to these higher smoking rates and lower quit rates. Smoking cessation interventions for people in rural and remote areas have been conducted, however little is known about their effectiveness or their mechanisms of action as well as the quality of such research. Behaviour change techniques (BCTs) are mechanisms of action derived from behaviour change theory, such as goal setting and reward. Improved understanding of the contribution of BCTs for smoking cessation in the rural and remote population will support future intervention development. We aim to review the literature on smoking cessation interventions for people living in rural and remote areas to inform evidence about intervention effectiveness and mechanisms of action. METHODS AND ANALYSIS: We will conduct a systematic review using seven scientific databases (EMBASE, MedLine, PsycINFO, CINAHL, Cochrane, Informit Health and Scopus). We will include peer-reviewed journal articles published in English that examine a smoking cessation intervention delivered to people living in rural and remote areas in the USA, Canada and Australia. We will examine outcome data relating to intervention effectiveness (eg, point prevalence abstinence or continuous abstinence), as well as the BCTs used in included interventions and their relationship with intervention outcomes. We will also assess the feasibility, acceptability and quality of research interventions of included articles, and provide graded recommendations based on the review outcomes. Data will be synthesised using narrative approaches and interpreted using content analysis. ETHICS AND DISSEMINATION: Ethics was not required for this systematic review. The results will be disseminated through peer-reviewed publication and at conferences by presentations. PROSPERO REGISTRATION NUMBER: 177398.

School students with chronic illness have unmet academic, social, and emotional school needs.

Students with chronic illness generally have higher school needs than their healthy peers. The research to date examining school support for these needs has been limited to qualitative methods. We collected quantitative data to compare the school needs and supports received by 192 students with chronic illness and 208 students without chronic illness using parent-completed surveys. We assessed school experiences and receipt of school support across academic, social-emotional, and medical domains and school attendance. We analyzed the data using logistic regression. Students with chronic illness were 3.8 times more likely to have repeated a grade, 3.6 times more likely to have parent-reported academic challenges, and 4.9 times more likely to have recent illness-related school absenteeism than healthy students. Parents of students with chronic illness were 2.2 times more likely to report their child to have moderate-high emotional distress, and 4.6 times more likely to report that their child had low social confidence compared with parents of healthy students. Students with chronic illness did not receive more school-based tutoring, home-based tutoring, or support from a teacher's aide or school psychologist than healthy students. Students with chronic illness receive insufficient support to address their academic and social-emotional needs or high rates of school absenteeism. Evidence-based educational services must be developed and delivered to meet the needs of students with chronic illness at school and while recovering at home.

Facilitating engagement with school in students with chronic illness through positive education: A mixed-methods comparison study.

Students with chronic illness may disengage from school, adversely affecting their school outcomes. Positive education targets students' social-emotional well-being (school well-being), which can increase engagement with school. We compared the relationship among positive educational practices, school well-being, and engagement with school as reported by parents of students with and without chronic illness. We used a convergent mixed-methods cross-sectional design. We collected data from 215 parents of school-age children with chronic illness and 212 parents of children without chronic illness. Data assessed positive educational practices, school well-being, and engagement with school, which we analyzed using regression and structural equation models. Forty-nine parents of students with chronic illness completed a telephone interview about their child's school experiences, which we analyzed using content analysis. School well-being was significantly lower among students with chronic illness, compared with students without chronic illness (p = .05). Higher student well-being (p ≤ .001) and higher levels of positive educational practices (p = .002) were associated with higher engagement with school. School well-being mediated the relationship between positive educational practices and engagement with school for students with chronic illness but not students without chronic illness. Parents of children with chronic illness described how positive educational practices and their child's school well-being promoted their child's engagement with school. Parents also reported the negative consequences of low school well-being. Positive educational practices alone may not be sufficient to increase engagement with school in students with low school well-being. Combined preventative and early intervention psychosocial support may best promote engagement with school in students with chronic illness.

A Systematic Review of Psychosocial Barriers and Facilitators to Smoking Cessation in People Living With Schizophrenia.

Background: People living with schizophrenia are less likely to quit smoking compared with the general population and people living with other psychiatric disorders. Understanding the schizophrenia-specific psychosocial barriers and facilitators to smoking cessation is important for designing effective smoking cessation interventions. We aimed to systematically review research examining psychosocial barriers and facilitators to smoking cessation in people living with schizophrenia. Methods: We followed the PRISMA statement to conduct a systematic literature review examining psychosocial barriers and facilitators to smoking cessation in people living with schizophrenia. We searched EMBASE, Medline, PsycINFO, and CINAHL databases from inception to 14 June 2018 to identify relevant articles. We included peer-reviewed original research articles that examined psychosocial barriers and facilitators to smoking cessation, as well as factors associated with maintenance of smoking habits in people living with schizophrenia spectrum disorders. Qualitative, quantitative, or mixed-methods study designs were included. Three authors screened titles, abstracts, and full-texts using the eligibility criteria. We conducted a narrative synthesis of the data to account for the heterogeneity of study designs. We analyzed qualitative and quantitative studies separately. Results: We identified 685 studies from our systematic search and screened the full-text of 134 articles. The final set of 23 articles included 20 quantitative studies and 3 qualitative studies. The most commonly cited barrier to smoking cessation in people living with schizophrenia was cravings and addiction, followed by a perceived increased risk of negative affect associated with quitting smoking. People living with schizophrenia reported smoking to manage stress and to maintain social relationships. People living with schizophrenia were found to be less likely to receive cessation support from health professionals than smokers without schizophrenia. Health concerns were the most commonly mentioned facilitator to quit smoking. Conclusions: People living with schizophrenia experience a wide range of barriers to smoking cessation. The influence of these barriers on smoking cessation likelihood may be greater among people living with schizophrenia than people without psychiatric disorders. Health professionals play an important role in smoking cessation for people living with schizophrenia and should consider barriers and facilitators identified in this review to support quitting in this vulnerable population.

Parents' Perspectives on Their Child's Social Experience in the Context of Childhood Chronic Illness: A Qualitative Study.

PURPOSE: Many children suffer from a serious chronic illness. These children have greater risks of developing psychosocial difficulties, associated with school absenteeism and missed social opportunities. Through parents' perspectives, this study aimed to gain a holistic understanding of children's social experience in the context of chronic illness. DESIGN AND METHODS: We conducted semi-structured interviews with parents of a child with a serious chronic illness exploring their child's school experience. Two researchers coded social experiences using an iterative process, involving regular team discussions. Theoretical thematic analysis and content analysis were both performed, using the social ecological model as a theoretical framework. RESULTS: Forty-nine parents participated (43 mothers, 6 fathers; child mean age 11.51 years; 21 female children, 28 male children; 6 different chronic illness groups). According to parents, the main facilitators to the social experience of their children involved parents themselves, the school, social networks and peers, as they were all able to provide social support and opportunities for social development. However, peers were also a source of bullying and peer pressure, and sometimes lacked understanding and empathy. CONCLUSIONS: As shown by the social ecological model, social functioning between chronically-ill children and their peers can be influenced by many factors. More specifically, parents have expressed their ability for promoting positive experiences between their children and their peers. Practice Implications Considering the complexity of social functioning, future research and interventions should provide holistic support for children with chronic illnesses.

Narrative Review of the Educational, Vocational, and Financial Needs of Adolescents and Young Adults with Cancer: Recommendations for Support and Research.

Adolescents and young adults (AYAs) with cancer have unique needs around education and vocation during and after treatment. This narrative review series aims at documenting the unique needs of AYAs from the current literature and at providing recommendations to inform an update of the Australian National Service Delivery Framework for AYAs with Cancer. AYAs with cancer may experience impairments to cognitive, physical, and psychological functioning and health, which can adversely affect their academic grades, peer relationships, and likelihood of entering the workforce. Treatment expenses and time off work can stifle AYAs' financial independence from their parents. The combined effect of disrupted education, vocation, and financial dependence can reduce AYAs' sense of identity. Although support is available in some countries, support efficacy is yet to be clearly established. Continued research is required to deliver successful education and work reintegration programs that build the confidence of AYAs with cancer to achieve their best. Educational and vocational support, as well as financial advice, may improve AYAs' financial security and quality of life during survivorship.

School Experiences of Siblings of Children with Chronic Illness: A Systematic Literature Review.

PROBLEM: Siblings of children with chronic illness have unique experiences that can affect their school functioning, such that they may miss ongoing periods of school, experience difficulties with schoolwork or experience changes in their peer and teacher interactions. This review provides an overview of these siblings' school experiences. ELIGIBILITY CRITERIA: Six databases (Medline, PsychINFO, CINAHL, ERIC, Embase and The Cochrane Library) were systematically searched for studies examining the school experiences and peer relationships of siblings of children with chronic illness, as well as school-based interventions for these siblings. Studies were included if they were published in or after 2000 and were published in English. SAMPLE: We identified 2137 articles upon initial search. From these, we identified 28 eligible studies examining the school experiences of >1470 siblings of children with chronic illness. RESULTS: Three key themes were identified throughout the reviewed articles. The literature described 1) the psychological impact on siblings at school; 2) decreases in school attendance and academic functioning, and; 3) changes or perceived differences in peer and teacher interactions. Siblings value teacher and peer support, and this support may contribute to better sibling school functioning. CONCLUSIONS: Many siblings are socially resilient, yet overlooked, members of the family who may present with psychological, academic and peer related difficulties at school following diagnosis of a brother or sister with chronic illness. IMPLICATIONS: Future research is needed to further delineate the sibling school experience to better facilitate the development of targeted sibling support interventions within the school environment.

A Web-Based Adolescent Positive Psychology Program in Schools: Randomized Controlled Trial.

BACKGROUND: Adolescent mental health is characterized by relatively high rates of psychiatric disorders and low levels of help-seeking behaviors. Existing mental health programs aimed at addressing these issues in adolescents have repeated inconsistent results. Such programs have generally been based on techniques derived from cognitive behavioral therapy, which may not be ideally suited to early intervention among adolescent samples. Positive psychology, which seeks to improve well-being rather than alleviate psychological symptoms, offers an alternative approach. A previous community study of adolescents found that informal engagement in an online positive psychology program for up to 6 weeks yielded significant improvements in both well-being and depression symptoms. However, this approach had not been trialed among adolescents in a structured format and within a school setting. OBJECTIVE: This study examines the feasibility of an online school-based positive psychology program delivered in a structured format over a 6-week period utilizing a workbook to guide students through website content and interactive exercises. METHODS: Students from four high schools were randomly allocated by classroom to either the positive psychology condition, "Bite Back", or the control condition. The Bite Back condition consisted of positive psychology exercises and information, while the control condition used a series of non-psychology entertainment websites. Both interventions were delivered online for 6 hours over a period of 4-6 weeks during class time. Symptom measures and measures of well-being/flourishing and life satisfaction were administered at baseline and post intervention. RESULTS: Data were analyzed using multilevel linear modeling. Both conditions demonstrated reductions in depression, stress, and total symptom scores without any significant differences between the two conditions. Both the Bite Back and control conditions also demonstrated significant improvements in life satisfaction scores post intervention. However, only the control condition demonstrated significant increases in flourishing scores post intervention. CONCLUSIONS: Results suggest that a structured online positive psychology program administered within the school curriculum was not effective when compared to the control condition. The limitations of online program delivery in school settings including logistic considerations are also relevant to the contradictory findings of this study.

Feasibility and effectiveness of a web-based positive psychology program for youth mental health: randomized controlled trial.

BACKGROUND: Youth mental health is a significant public health concern due to the high prevalence of mental health problems in this population and the low rate of those affected seeking help. While it is increasingly recognized that prevention is better than cure, most youth prevention programs have utilized interventions based on clinical treatments (eg, cognitive behavioral therapy) with inconsistent results. OBJECTIVE: This study explores the feasibility of the online delivery of a youth positive psychology program, Bite Back, to improve the well-being and mental health outcomes of Australian youth. Further aims were to examine rates of adherence and attrition, and to investigate the program's acceptability. METHODS: Participants (N=235) aged 12-18 years were randomly assigned to either of two conditions: Bite Back (n=120) or control websites (n=115). The Bite Back website comprised interactive exercises and information across a variety of positive psychology domains; the control condition was assigned to neutral entertainment-based websites that contained no psychology information. Participants in both groups were instructed to use their allocated website for 6 consecutive weeks. Participants were assessed pre- and postintervention on the Depression Anxiety Stress Scale-Short form (DASS-21) and the Short Warwick-Edinburgh Mental Well-Being Scale (SWEMWBS). RESULTS: Of the 235 randomized participants, 154 (65.5%) completed baseline and post measures after 6 weeks. Completers and dropouts were equivalent in demographics, the SWEMWBS, and the depression and anxiety subscales of the DASS-21, but dropouts reported significantly higher levels of stress than completers. There were no differences between the Bite Back and control conditions at baseline on demographic variables, DASS-21, or SWEMWBS scores. Qualitative data indicated that 49 of 61 Bite Back users (79%) reported positive experiences using the website and 55 (89%) agreed they would continue to use it after study completion. Compared to the control condition, participants in the Bite Back condition with high levels of adherence (usage of the website for 30 minutes or more per week) reported significant decreases in depression and stress and improvements in well-being. Bite Back users who visited the site more frequently (≥3 times per week) reported significant decreases in depression and anxiety and improvements in well-being. No significant improvements were found among Bite Back users who demonstrated low levels of adherence or who used the website less frequently. CONCLUSIONS: Results suggest that using an online positive psychology program can decrease symptoms of psychopathology and increase well-being in young people, especially for those who use the website for 30 minutes or longer per week or more frequently (≥3 times per week). Acceptability of the Bite Back website was high. These findings are encouraging and suggest that the online delivery of positive psychology programs may be an alternate way to address mental health issues and improve youth well-being nationally.
