Early outcomes of referrals to the English National Health Service Digital Weight Management Programme.

OBJECTIVE: The study objective was to assess participant weight change for the English National Health Service (NHS) Digital Weight Management Programme, the first such digital intervention to achieve population coverage. METHODS: A service evaluation was used to assess intervention effectiveness for adults with obesity and a diagnosis of hypertension and/or diabetes, between April 2021 and March 2022, using prospectively collected, national service-level data in England. RESULTS: Of the 63,937 referrals made from general practices, within the time period, 31,861 (50%) chose to take up the 12-week Programme. There were 31,718 participants who had time to finish the Programme; of those, 14,268 completed the Programme (defined as attending ≥60%), a 45% completion rate. The mean weight change for those who had time to finish the Programme was -2.2 kg (95% CI: -2.25 to -2.16), for those who completed it was -3.9 kg (95% CI: -3.99 to -3.84), and for those who had time to finish the Programme but did not complete it was -0.74 kg (95% CI: -0.79 to -0.70). CONCLUSIONS: The NHS Digital Weight Management Programme is effective at achieving clinically meaningful weight loss. The outcomes compare favorably to web-based weight management interventions tested in randomized trials and those delivered as face-to-face interventions, and results suggest that the approach may, with increased participation, bring population-level benefits.

Effectiveness of acceptance and commitment therapy for improving quality of life and mood in individuals with multiple sclerosis: A systematic review and meta-analysis.

OBJECTIVE: To review the evidence for the effectiveness of Acceptance and Commitment Therapy (ACT) intervention on quality of life and mood, for individuals with Multiple Sclerosis (MS). METHOD: A systematic search was conducted of PsycINFO, CINAHL, Embase, MEDLINE, Web of Science, Scopus and ContextualScience.org up to 13/01/2022. Grey literature was also searched via ProQuest Dissertations and Theses, and PROSPERO. We included Randomised Controlled Trials (RCTs) published in English, that examined the effectiveness of ACT for people with a diagnosis of MS. We were interested in outcomes of Quality of Life (QoL), mood (e.g., anxiety, depression and stress), and ACT-targeted processes. Methodological quality was assessed using the Cochrane Risk of Bias Tool v2. Where available, the extracted data were entered into a meta-analysis to determine weighted effect size estimates for the outcomes of interest. RESULTS: Six studies (191 participants), out of 142 identified, met inclusion criteria. Meta-analyses indicated a statistically significant small effect on stress (SMD = -0.49 [95% CI of -0.89 - -0.08]), in favour of ACT. There were no statistically significant effects of ACT on anxiety (SMD = -0.41 [95% CI of -0.93 - 0.11]), depression (SMD = -0.92 [95% CI of -1.91 - 0.06]), or ACT-targeted processes (SMD = -0.18 [95% CI of -0.62 - 0.25]). There was a small, nonsignificant effect on QoL, in favour of control conditions (SMD=0.39 [95% CI of -0.08 - 0.85]). Methodological quality of the studies was variable; all but one study had at least one high risk of bias. CONCLUSIONS: Findings suggest a small effect of ACT on reducing stress for people with MS, but not reducing anxiety or depression, or improving quality of life. Due to small sample sizes and few studies within this area, generalisability of findings is limited. Future trials should be pay more attention to methodological rigour.

Natural Language Processing markers in first episode psychosis and people at clinical high-risk.

Recent work has suggested that disorganised speech might be a powerful predictor of later psychotic illness in clinical high risk subjects. To that end, several automated measures to quantify disorganisation of transcribed speech have been proposed. However, it remains unclear which measures are most strongly associated with psychosis, how different measures are related to each other and what the best strategies are to collect speech data from participants. Here, we assessed whether twelve automated Natural Language Processing markers could differentiate transcribed speech excerpts from subjects at clinical high risk for psychosis, first episode psychosis patients and healthy control subjects (total N = 54). In-line with previous work, several measures showed significant differences between groups, including semantic coherence, speech graph connectivity and a measure of whether speech was on-topic, the latter of which outperformed the related measure of tangentiality. Most NLP measures examined were only weakly related to each other, suggesting they provide complementary information. Finally, we compared the ability of transcribed speech generated using different tasks to differentiate the groups. Speech generated from picture descriptions of the Thematic Apperception Test and a story re-telling task outperformed free speech, suggesting that choice of speech generation method may be an important consideration. Overall, quantitative speech markers represent a promising direction for future clinical applications.

Lower speech connectedness linked to incidence of psychosis in people at clinical high risk.

BACKGROUND: Formal thought disorder is a cardinal feature of psychotic disorders, and is also evident in subtle forms before psychosis onset in individuals at clinical high-risk for psychosis (CHR-P). Assessing speech output or assessing expressive language with speech as the medium at this stage may be particularly useful in predicting later transition to psychosis. METHOD: Speech samples were acquired through administration of the Thought and Language Index (TLI) in 24 CHR-P participants, 16 people with first-episode psychosis (FEP) and 13 healthy controls. The CHR-P individuals were then followed clinically for a mean of 7 years (s.d. = 1.5) to determine if they transitioned to psychosis. Non-semantic speech graph analysis was used to assess the connectedness of transcribed speech in all groups. RESULTS: Speech was significantly more disconnected in the FEP group than in both healthy controls (p < .01) and the CHR-P group (p < .05). Results remained significant when IQ was included as a covariate. Significant correlations were found between speech connectedness measures and scores on the TLI, a manual assessment of formal thought disorder. In the CHR-P group, lower scores on two measures of speech connectedness were associated with subsequent transition to psychosis (8 transitions, 16 non-transitions; p < .05). CONCLUSION: These findings support the utility and validity of speech graph analysis methods in characterizing speech connectedness in the early phases of psychosis. This approach has the potential to be developed into an automated, objective and time-efficient way of stratifying individuals at CHR-P according to level of psychosis risk.

Discovery awareness for staff supporting individuals with intellectual disabilities and challenging behaviour: is it helpful and does it increase self-efficacy?

Discovery awareness (DA) is an approach to using video within structured meetings to help staff become more mindful, aware and interested in a client they are supporting who has intellectual disabilities and challenging behaviour. The objective was to evaluate whether, and how, DA is helpful for staff in both inpatient and community settings, and whether it increases self-efficacy in working with people with challenging behaviour. A two-phase mixed method design was employed. For phase 1, forty staff who took part in one of seven single DA meetings completed the Challenging Behaviour Self-Efficacy Scale pre- and post-DA. In addition, post-DA, participants completed an Adapted Helpful Aspects of Therapy Scale (AHAT). For phase 2, six participants completed a follow-up Change Interview; 3-12 weeks after DA. Descriptive statistics reveal participants found events in the DA 'greatly helpful'. The changes identified varied in whether they were expected or not, but were unlikely to occur without DA and 'very important'. Statistical analysis showed no significant changes in self-efficacy following the DA. A thematic analysis on the qualitative data generated by the change interviews and AHAT identified three main themes: Impact on interaction; DA is unique and valuable; and the power of the process. The latter had three subthemes: a structure to facilitate change, making use of the content and reflective space to promote learning. Attendance at a single DA meeting does not increase staff perceptions of self-efficacy, however, staff find the process of DA helpful as it encourages reflection on their interactions with individuals with intellectual disability and challenging behaviour and attuning of their interactions, though further research is needed.
