    Mobile enhancement of motivation in schizophrenia: A pilot trial of a personalized text message intervention for motivation deficits
    (Cambridge University Press, 2018-05-10) Luther, Lauren; McCormick, Bryan P.; Lapish, Christopher C.; Salyers, Michelle P.; Medicine, School of Medicine
    OBJECTIVES/SPECIFIC AIMS: Motivation deficits are one of the strongest determinants of poor functional outcomes in people with schizophrenia. Mobile interventions are a promising approach to improving these deficits, as they can provide frequent cues and reinforcements that support goal-directed behavior. The objective of this study is to describe the intervention protocol and initial effectiveness of a personalized mobile text message intervention, Mobile Enhancement of Motivation in Schizophrenia (MEMS). METHODS/STUDY POPULATION: This pilot study will examine the effects of MEMS compared with a control group using a randomized design. Up to 40 outpatients with a schizophrenia-spectrum disorder will be recruited. All participants will set individualized recovery goals to complete over an 8-week period; those randomized to receive MEMS will also receive 3 sets of personalized, interactive text messages each weekday to reinforce and cue goal completion. Before and after the 8-week period, participants in both groups will complete validated measures of motivation, quality of life, and functioning. Both groups will also report their goal attainment after 8 weeks. RESULTS/ANTICIPATED RESULTS: It is anticipated that those in the MEMS group will demonstrate greater goal attainment and improvements in motivation, quality of life, and functioning compared with the control group. DISCUSSION/SIGNIFICANCE OF IMPACT: This project will test the initial effectiveness of a novel intervention for improving one of the most debilitating aspects of schizophrenia.

    Mobile Enhancement of Motivation in Schizophrenia: A Pilot Trial of a Personalized Text-Message Intervention for Motivation Deficits

    Motivation deficits remain an unmet treatment need in schizophrenia. Recent preclinical research has identified novel mechanisms underlying motivation deficits, namely impaired effort-cost computations and reduced future reward-value representation maintenance, that may serve as more effective treatment targets to improve motivation. The main aim of this study was to test the feasibility and preliminary effectiveness of a translational mechanism-based intervention, MEMS (Mobile Enhancement of Motivation in Schizophrenia), which leverages mobile technology to target these mechanisms with text-messages. Fifty-six participants with a schizophrenia-spectrum disorder were randomized to MEMS (n = 27) or a control condition (n = 29). All participants set recovery goals to complete over eight-weeks. The MEMS group also received personalized, interactive text-messages each weekday to support motivation. Retention and engagement in MEMS was high: 92.6% completed 8 weeks of MEMS, with an 86.1% text-message response rate, and 100% reported that they were satisfied with the text-messages. Compared to the control condition, the MEMS group had significantly greater improvements in interviewer-rated motivation and anticipatory pleasure and obtained significantly more recovery-oriented goals at the end of the 8-week period. There were no significant group differences in performance-based effort-cost computations and future reward-value representations, self-reported motivation, quality of life, functioning, or additional secondary outcomes of positive symptoms, mood symptoms, or neurocognition. Results suggest that MEMS is feasible as a relatively brief, low-intensity mobile intervention that could effectively improve interviewer-rated motivation, anticipatory pleasure, and recovery goal attainment in those with schizophrenia-spectrum disorders.
