BackgroundLimited time management skills cause problems in daily life for people with mild intellectual disability (ID) and "Lets Get Organized" (LGO) is a promising manual-based occupational therapy group intervention aiming to support management skills.Aims/ObjectivesTo evaluate the applicability of the Swedish version of LGO-S by i) exploring enhancements in time management skills, satisfaction with daily occupations, and aspects of executive functioning in people with time-management difficulties and mild ID, and ii) describing clinical experiences of using the LGO-S for people with mild ID.Material and methodsTwenty-one adults with mild ID were included. Data were collected pre-/post-intervention and at 3- and 12-month follow-ups with: Swedish version of Assessment of Time Management Skills (ATMS-S), Satisfaction with Daily Occupation (SDO-13), and Weekly Calendar Planning Activity (WCPA-SE). There were few follow-up participants (n = 6-9).ResultsSignificant change in time management skills that maintained at 12-months follow-ups. Significant increase in regulation of emotions at 12-month follow-up. Results at 12-months follow-up indicated sustainability in outcomes as measured by ATMS-S. A non-significant positive trend was observed in other outcomes between pre- and post-intervention.Conclusions and significanceLGO-S seems applicable for improving skills in time management, organisation and planning also for people with mild ID.
