Inferring sleep disturbance from text messages of suicide attempt survivors: A pilot study.

ABSTRACT:

Objective

Identifying digital markers of sleep disturbance-a known suicide risk factor-may aid in the detection of imminent suicide risk. This study examined sleep-related communication and texting patterns in personal text messages (N = 86,705) of suicide attempt survivors.

Method

Twenty-six participants provided dates of past suicide attempts and 2-week periods of positive mood, depressed mood, or suicidal ideation. Linguistic Inquiry Word Count was used to identify sleep-related texts via a custom dictionary. Mixed effect models were fitted to test the association between suicide/mood episode type (e.g., attempt versus ideation) and three outcomes: likelihood of a text including sleep-related content, nightly count of texts sent from midnight to 5:00 AM, and sum of unique hour bins from midnight to 5:00 AM with outgoing texts.

Results

Analyses with a sleep dictionary that was manually revised to be more accurate (but not the original unedited dictionary) showed sleep-related communication was more likely during depressed mood episodes than positive mood episodes. Otherwise, there were no significant differences in sleep-related communication or objective texting patterns across episode type.

Conclusions

Although we did not detect differences in sleep-related communication tied to suicidal thoughts or behaviors, sleep-related communication may differ as a function of within-person mood level.

Project description:BackgroundSuicide attempts have a profound emotional impact on both individuals and society as a whole. This qualitative study delves into three key aspects: 1) the progression through the suicidal process, 2) the influential factors facilitating the transition from ideation to attempt using the volitional moderators within the integrated motivational-volitional (IMV) model, and 3) preventive strategies impeding this transition from ideation to attempt.MethodsBetween October 1, 2022 and March 7, 2023 we interviewed 27 adults (23 women, four men, mean age 33 years) who attempted suicide within the past 12 months. Participants were recruited through social media and in collaboration with several mental health institutions in the Netherlands. The participants were initially screened and interviewed based on the Pathway to Suicidal Actions Interview. Analysis was performed employing the constant comparative method.FindingsDespite the heterogeneity of the suicidal process, suicidal thoughts predominately emerged during adolescence (Mdn = 15, M = 17.8). In most participants, planning and preparatory actions occurred long before the attempt, with a median of six years prior to the attempt for the selection of the method. All volitional moderators were observed, although pain sensitivity in particular varied among participants. Access to lethal means and planning emerged as important moderators in the suicidal process. Asking the survivors what could have helped to prevent their attempts, most participants mentioned that they felt their suicidality was not taken seriously enough.InterpretationWe discussed the significance of planning in the suicidal process, challenges in conceptualizing planning and impulsivity, and individual differences in pain sensitivity. Based on the findings, we underscore the critical need for restricting access to means, giving greater consideration to preparatory actions within the suicidal process, and fostering open dialogues about suicidality.FundingThis research was funded by ProRail, the Dutch rail infrastructure manager in line with their work on mental health.

Project description:BackgroundOver 1.3 million people live with colorectal cancer in the United States. Physical activity is associated with lower risk of colorectal cancer recurrence and mortality. Interventions are needed to increase physical activity in colorectal cancer survivors.MethodsWe conducted a 2-arm non-blinded pilot randomized controlled trial at the University of California, San Francisco among 42 individuals who had completed curative-intent treatment for colorectal cancer to determine the feasibility and acceptability of a 12-week (84 days) physical activity intervention using a Fitbit Flex™ and daily text messages. Participants were randomized 1:1 to receive the intervention with print educational materials or print educational materials alone. We explored the impact of the intervention versus usual care on physical activity using ActiGraph GT3X+ accelerometers pre-/post-intervention.ResultsWe screened 406 individuals and randomized 42 to intervention (n = 21) or control (n = 21) groups. During the 12-week study, the intervention arm wore their Fitbits a median of 74 days [88% of days in study period, interquartile range: 23-83 days] and responded to a median of 34 (out of 46) text messages that asked for a reply (interquartile range: 13-38 text messages). Among the 16 intervention participants who completed the feedback survey, the majority (88%) reported that the intervention motivated them to exercise and that they were satisfied with their experience. No statistically significant difference in change in moderate-to-vigorous physical activity was found from baseline to 12 weeks between arms.ConclusionA 12-week physical activity intervention with a Fitbit and text messages was feasible and acceptable among colorectal cancer patients after curative treatment. Larger studies are needed to determine whether the intervention increases physical activity.Trial registrationClinicaltrials.gov Identifier NCT02966054 .

Project description:BackgroundSuicidal behaviour and deliberate self-harm are common among adults. Research indicates that maintaining contact either via letter or postcard with at-risk adults following discharge from care services can reduce reattempt risk. Feasibility trials demonstrated that intervention through text message was also effective in preventing suicide repetition amongst suicide attempters. The aim of the current study is to investigate the effect of text message intervention versus traditional treatment on reducing the risk of suicide attempt repetition among adults after self-harm.Methods/designThe study will be a 2-year multicentric randomized controlled trial conducted by the Brest University Hospital, France. Participants will be adults discharged after self-harm, from emergency services or after a short hospitalization. Participants will be recruited over a 12-month period. The intervention is comprised of an SMS that will be sent at h48, D7, D15 and monthly. The text message enquires about the patients' well-being and includes information regarding individual sources of help and evidence-based self help strategies. Participants will be assessed at the baseline, month 6 and 13. As primary endpoint, we will assess the number of patients who reattempt suicide in each group at 6 months. As secondary endpoints, we will assess the number of patients who reattempt suicide at 13 month, the number of suicide attempts in the intervention and control groups at 6 and 13 month, the number of death by suicide in the intervention and control groups at month 6 and 13. In both groups, suicidal ideations, will be assessed at the baseline, month 6 and 13. Medical costs and satisfaction will be assessed at month 13.DiscussionThis paper describes the design and deployment of a trial SIAM; an easily reproducible intervention that aims to reduce suicide risk in adults after self-harm. It utilizes several characteristics of interventions that have shown a significant reduction in the number of suicide reattempts. We propose to assess its efficacy in reducing suicide reattempt in the suicide attempter (SA) population.Trial registrationThe study was registered on Clinical Trials Registry (clinicaltrials.gov): NCT02106949, registered on 06 June 2014.
