Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Common mental health problems (CMHPs) give rise to large costs and much unnecessary suffering. Most patients with these problems are found in primary care. Positive effects of psychological treatment are well documented, but primary care is failing in the implementation of evidence-based treatments. Aims: The overarching aim of this thesis was to contribute to the comprehension of how digital and transdiagnostic interventions can enhance accessibility to interventions to improve lifestyle behaviors and mental health in primary care settings. Study I aimed to explore two aspects: a) healthcare clinicians' perceptions and experiences of working with lifestyle behaviors, and b) their preferences and requirements for adopting a more systematic approach in the future. Study II aimed to assess the feasibility of a digital lifestyle behavior intervention for patients seeking help for CMHPs. Participants were offered a digital support giving feedback on their lifestyle behaviors and offering guidance on making lifestyle changes. Study III aimed to investigate the feasibility of a transdiagnostic video-based course designed for patients seeking psychological treatment for CMHPs in primary care. Study IV sought to elucidate the documented effects of transdiagnostic digital interventions for patients with depression and/or anxiety in a systematic review and meta-analysis. Methods: In Study I, semi-structured focus group interviews were carried out at 10 primary care clinics in Sweden. Participants were health care professionals from different professions (N=46). Data was analyzed using a phenomenological-hermeneutic model. Study II was a pilot study with an embedded randomized controlled trial (RCT; N=152), and also measured feasibility outcomes such as the inclusion rate, proportion of unhealthy lifestyle behaviors in the sample, adherence to the protocol and missing data. Participants in both groups also completed depression and anxiety self-ratings at baseline and 10 weeks later. Study III employed a single-group prospective cohort design (N=91). Main feasibility measures included participant satisfaction, attendance rates, the percentage of participants in need of additional psychological intervention when the course was finished, and proportion of clinically significant improvement. Study IV was a systematic review and meta-analysis of RCTs investigating internet-delivered transdiagnostic treatments for individuals with clinical depression, anxiety, or both. All age groups, all treatment schools and both guided and unguided interventions were included. Results: In Study I, two major themes emerged: 1) the need for structured professional practice and 2) deficient professional practice as an obstacle for implementation of healthy lifestyle promotion. In Study II, the recruitment rate was initially low but increased after further involvement of the clinicians and an increased frequency of contact with the patients. The 10-week missing data rate was 33/152 (22%). Fewer than half of the participants (38%, n=58/152) had at least one type of high-risk behavior at baseline. Psychiatric symptoms were moderate at baseline and declined in both groups after 10 weeks (d=0.57-0.75), but there were no between-group differences. In Study III, the mean score on the Client Satisfaction Questionnaire-8 was 21.8 (SD=4.0, 9-32, n= 86), just below the a priori target of 22. On average, the participants attended 5.0/6 sessions (SD=1.6, range 0-6, n=91). Almost half of the sample (46%; 37/81) reported not needing further psychological treatment after the course. Of patients with elevated anxiety symptoms, 59% (27/46) showed clinically significant improvement. The corresponding improvement for depression was 48% (22/46). The missing data rate at post treatment was 5/91 (5%). No serious adverse events were reported. In Study IV, 57 trials with 21795 participants were included. Large within-group reductions were seen for working age adults in symptoms of depression (g=0.90; 95% CI 0.81-0.99) and anxiety (g=0.87; 95% CI 0.78-0.96). Compared to treatment-as-usual and waitlist controls (WLC’s), the added effects were moderate (depression: g = 0.52; 95% CI 0.42-0.63; anxiety: g=0.45; 95% CI 0.34-0.56). Compared to attention/engagement controls, the added effects were small (depression: g=0.30; 95% CI 0.07-0.53; anxiety: g=0.21; 95% CI 0.01-0.42). Heterogeneity was substantial. Two trials concerned adolescents and reported mixed results. One trial concerned older adults and reported promising results. Three trials reported having been conducted in a primary care setting. Conclusions: Study I showed that it was crucial to explicitly define digital interventions as complements to face-to-face meetings in primary care, in an effort to promote evidence-based practice and lighten the burden of health professionals. In Study II, recruitment routines seemed to be decisive for reaching as many patients as possible. The relatively low rate of unhealthy lifestyle behaviors and small effect sizes suggest that the Health Profile intervention evaluated may only suit patients at risk. In Study III, it appeared feasible to deliver an early access mental health course through video in a primary care setting, indicating that it would be of interest to evaluate course effects in a future RCT. In Study IV, internet-delivered transdiagnostic treatments for both depression and anxiety showed added effects that were small to moderate, varying by control condition. Research is needed regarding routine care and age groups other than working-age adults.

- BACKGROUND: In many health care systems, primary care is tasked with offering psychological treatment for common mental disorders. Resources are often limited, which complicates widespread dissemination of traditional psychological treatments. Stepped care models where the less resource-intensive interventions are delivered first, can be employed, but often do not eliminate the need for a thorough diagnostic assessment, which can be time-consuming, has the potential to bottleneck patient intake, and can add to waiting times. Novel low-threshold formats are needed to improve access to mental health care in the primary care setting.METHODS: This was a single-group prospective cohort study (N = 91). We assessed the feasibility of a video-delivered course as a first-line intervention for patients seeking help for mental health problems at a primary care center. The course had a transdiagnostic approach, suitable for both depression and anxiety disorders, and was based on cognitive behavioral techniques. Patients in need of psychosocial assessment, which usually entailed a four- to six-week wait, were referred by physicians or triage nurses. Study participants could start within a week, without the need for conventional diagnostic assessment, and were informed that they would be offered assessment after the course if needed. Key feasibility outcomes included participant satisfaction, attendance rates, the proportion of participants in need of additional clinical intervention after the course, and the rate of clinically significant improvement in anxiety and depression symptoms.RESULTS: Participants scored a mean of 21.8 (SD = 4.0, 9-32, n = 86) on the Client Satisfaction Questionnaire-8; just below our target of 22. The mean attendance rate was 5.0/6 lectures (SD = 1.6, range: 0-6, n = 91). Forty-six percent (37/81) reported experiencing no need of further clinical intervention after the course. The rate of clinically significant improvement was 59% (27/46) for anxiety and 48% (22/46) for depression. No serious adverse event was reported.CONCLUSIONS: Delivering a low-threshold online video-delivered mental health course in primary care appears to be feasible. Adjustments to further improve patient satisfaction are warranted, such as offering the choice of participating online or face-to-face.TRIAL REGISTRATION: (ClinicalTrials.gov NCT04522713) August 21, 2020.

- Aim:This study piloted a digital self-help intervention facilitating healthy lifestyle for patients with mental health problems in primary care.Background:Patients with mental health problems show more unhealthy lifestyle behaviors than the general population and prior research indicates that healthy lifestyle behaviors can improve mental health.Methods:This pilot study assessed use of a self-help digital intervention for healthy lifestyle promotion and included an embedded randomized recruitment trial, where all patients were randomized to digital self-help plus treatment as usual (TAU) or to TAU only. Patients seeking help for mental health problems were recruited from two primary care clinics in Stockholm, Sweden, and offered participation in a healthy lifestyle promotion study via digital self-help. Outcome measures included use-related assessment of inclusion and follow-up rates at both clinics, participant characteristics, and intervention adherence. Secondary outcomes included depression (the Patient Health Questionnaire-9) and anxiety (the GAD-7) up to 10 weeks, and changes in alcohol and tobacco use, physical activity, and diet.Results:The study included 152 patients. The recruitment rate, initially low, increased after involving the clinicians more and maintaining more frequent contact with the patients. The 10-week missing data rate was 33/152 (22%). Participants were 70% (106/152) women, with a mean age of 42 years (SD = 14); fewer than half (38%, n = 58/152) had one or more high-risk unhealthy behaviors at inclusion. Psychiatric symptoms were moderate at baseline and declined in both groups after 10 weeks (d = 0.57-0.75). No between-group effects over time occurred on depression (b = 0.3 [95% CI -1.6, 2.2]; d = 0.06), anxiety (b = -0.7 [-2.5, 1.2]; d = 0.13), or lifestyle behaviors (b = 0.01 [-0.3, 0,3]; d = -0.01).Conclusions:Recruitment routines seemed to be decisive for reaching as many patients as possible. The relatively low rate of unhealthy lifestyle behaviors and small effect sizes suggests that the intervention may only suit patients at risk.Trial registration:ClinicalTrials.gov NCT03691116 (01/10/2018), focusing on the embedded trial. Retrospectively registered for the first clinic and prospectively for the second clinic.

- Objective: Depression and anxiety are major public health problems. This study evaluated the effects of internet-delivered transdiagnostic psychological treatments for individuals with depression, anxiety, or both.Design: Systematic review with meta-analysis.Data sources: Medline (Ovid), Cochrane Library (Wiley), the Web of Science Core Collection (Clarivate), and PsycInfo (EBSCO) were searched on 24 May 2021, with an update on 6 February 2023.Eligibility criteria: Randomised controlled trials of internet-delivered transdiagnostic psychological treatments, open to both participants with primary depression and participants with primary anxiety. This review concerned all treatment frameworks, both guided and unguided formats and all age groups.Data extraction and synthesis: In random-effects meta-analysis, we estimated pooled effects on depression symptoms and anxiety in terms of Hedges' g with 95% CIs. Absolute and relative heterogeneity was quantified as the tau(2) and I-2.Results: We included 57 trials with 21 795 participants. Nine trials (16%) recruited exclusively from routine care, and three (5%) delivered treatment via video. For adults, large within-group reductions were seen in depression (g=0.90; 95% CI 0.81 to 0.99) and anxiety (g=0.87; 95% CI 0.78 to 0.96). Compared with rudimentary passive controls, the added effects were moderate (depression: g=0.52; 95% CI 0.42 to 0.63; anxiety: g=0.45; 95% CI 0.34 to 0.56) and larger in trials that required all participants to meet full diagnostic criteria for depression or an anxiety disorder. Compared with attention/engagement controls, the added effects were small (depression: g=0.30; 95% CI 0.07 to 0.53; anxiety: g=0.21; 95% CI 0.01 to 0.42). Heterogeneity was substantial, and the certainty of the evidence was very low. Two trials concerned adolescents and reported mixed results. One trial concerned older adults and reported promising results.Conclusion: Internet-delivered transdiagnostic treatments for depression and anxiety show small-to-moderate added effects, varying by control condition. Research is needed regarding routine care, the video format, children and adolescents and older adults.
