- Stress is a major health problem in today's workplace. Recent studies suggest that acceptance and commitment therapy (ACT) is effective for reducing stress at work, specifically among managers. Moreover, smartphone-delivered treatments have been developed and increasingly used in research. The objective of our study was to evaluate the efficacy of an ACT-based smartphone treatment among middle managers at medium- and large-sized companies (> 50 employees) in Sweden. A total of 73 participants were randomized to either receive the six-week stress intervention (n = 36) or to a waitlist control group (n = 37). Results showed small to moderate within-group effect sizes (Cohen's d range 0.37–0.62) for the treatment group, and small to moderate between group effects (Cohen's d range 0.41–0.50). In conclusion, the study indicates that a smartphone administered stress intervention based on ACT can reduce perceived stress and increase general health among Swedish middle managers in the private sector.

- Objectives Evaluating and comparing the effectiveness of two smartphone-delivered treatments: one based on behavioural activation (BA) and other on mindfulness. Design Parallel randomised controlled, open, trial. Participants were allocated using an online randomisation tool, handled by an independent person who was separate from the staff conducting the study. Setting General community, with recruitment nationally through mass media and advertisements. Participants 40 participants diagnosed with major depressive disorder received a BA treatment, and 41 participants received a mindfulness treatment. 9 participants were lost at the post-treatment. Intervention BA: An 8-week long behaviour programme administered via a smartphone application. Mindfulness: An 8-week long mindfulness programme, administered via a smartphone application. Main outcome measures The Beck Depression Inventory-II (BDI-II) and the nine-item Patient Health Questionnaire Depression Scale (PHQ-9). Results 81 participants were randomised (mean age 36.0years (SD=10.8)) and analysed. Results showed no significant interaction effects of group and time on any of the outcome measures either from pretreatment to post-treatment or from pretreatment to the 6-month follow-up. Subgroup analyses showed that the BA treatment was more effective than the mindfulness treatment among participants with higher initial severity of depression from pretreatment to the 6-month follow-up (PHQ-9: F (1, 362.1)=5.2, p<0.05). In contrast, the mindfulness treatment worked better than the BA treatment among participants with lower initial severity from pretreatment to the 6-month follow-up (PHQ-9: F (1, 69.3)=7.7, p<0.01); BDI-II: (F(1, 53.60)=6.25, p<0.05). Conclusions The two interventions did not differ significantly from one another. For participants with higher severity of depression, the treatment based on BA was superior to the treatment based on mindfulness. For participants with lower initial severity, the treatment based on mindfulness worked significantly better than the treatment based on BA. Trial registration Clinical Trials NCT01463020.

- Purpose: In light of the research support for behavioral activation, and the promising findings of smartphone-delivered psychological interventions in the treatment of depression, we evaluated a smartphone depression application as an adjunct to four face-to-face sessions (blended treatment) for mild to moderate depression. The blended treatment was compared to a full 10-session treatment with no support from a smartphone. Methods: This was a non-inferiority study with unrestricted randomization in a 1:1 ratio. The study was conducted at three clinics in Sweden. 45 participants diagnosed with major depressive disorder received the blended treatment, and 43 participants received the full 10-session treatment. Main outcome measures were the BDI-II and the PHQ-9. Results: Results showed significant improvements in both groups across time on the primary outcome measures (within-group Cohen’s d range 1.51–1.80; between group d range −0.21– 0.01), indicating non-inferiority of the blended treatment, and at the same time with an average 44.6% reduction of therapist time. Conclusions: The blended treatment was non-inferior to the full behavioural treatment, and at the same time reduced therapist time. This may have important implications for planning psychological services. Moreover, from a theoretical point of view, the trial could be important as it tests the possibility to integrate modern information technology with face-to-face therapy.
