Brief Summary

Disparities in diagnosis and control of type 2 diabetes mellitus are most evident in African Americans (AAs) with lower socioeconomic status. Health literacy is an important predictor of adequate self-management and control of diabetes. The purpose of this pilot study was to test the feasibility and preliminary efficacy of a health literacy-enhanced diabetes intervention -Prevention through Lifestyle intervention And Numeracy (PLAN) 4 Success-Diabetes, in inner-city, low-income AAs with uncontrolled diabetes. To evaluate the feasibility, acceptability, and preliminary efficacy of the intervention, the investigators conducted a pilot study with 24-week follow-up. The investigators that participation in the PLAN 4 Success-diabetes intervention would be associated with a reduction in glucose outcomes and improvements in psychosocial variables.

Outcome Measures

Primary Outcomes (2)

  • Change in Health literacy as assessed by Literacy Assessment in Diabetes (LAD).

    The Literacy Assessment in Diabetes (LAD) has high reliability and validity indices. The items on the LAD are scored as correct/incorrect, with total possible scores ranging from 0 to 60. Higher scores indicated higher health literacy levels.

    baseline; 12 and 24 weeks

  • Change in Health literacy as assessed by the Newest Vital Sign

    The Newest Vital Sign consists of four items and measures numeracy. After reviewing a nutrition label, participants are asked to answer questions based on some calculation of the nutritional information (e.g., fat, sodium) presented on the label. Total possible scores range from 0 to 4, with one point assigned for each correct response.

    baseline; 12 and 24 weeks

Secondary Outcomes (2)

  • Change in Diabetes knowledge measured with the validated Diabetes Knowledge Test

    baseline; 12 and 24 weeks

  • Change in Diabetes self-efficacy measured with Stanford Diabetes Self-Efficacy scale

    baseline; 12 and 24 weeks

Other Outcomes (4)

  • Change in Diabetes self-care index

    baseline; 12 and 24 weeks

  • Change in Social support as assessed by modified Medical Outcomes Study-Social Support Survey (mMOS-SS)

    baseline; 12 and 24 weeks

  • Change in Depression status as assessed by the Patient Health Questionnaire (PHQ)-9

    baseline; 12 and 24 weeks

  • +1 more other outcomes

Study Arms (1)

Intervention

EXPERIMENTAL

This is a one arm study with all participants enrolled into this arm.

Behavioral: PLAN 4 Success-Diabetes

Interventions

The study intervention-PLAN 4 Success-Diabetes-consisted of four 1 to 1 ½-hour weekly health literacy training and disease knowledge education sessions for four weeks (4 in-person sessions), followed by two home visits and monthly phone counseling for over 6 months (5 phone sessions). The intervention is theory-driven and builds on von Wagner's model to incorporate key elements such as health literacy, disease knowledge, and self-efficacy for better glucose outcomes.

Model Details: The investigators used a single-arm pre- and post-test design for this pilot study in which the investigators assessed the feasibility, acceptability, and preliminary efficacy of the PLAN 4 Success-Diabetes in inner-city AAs in Baltimore, Maryland. Community-dwelling AAs were recruited via referrals from inner-city federally-qualified health clinics. Nineteen of 30 participants who completed the baseline survey received the study intervention which consisted of four-week health literacy training and disease knowledge education followed by two home visits and monthly phone counseling for over 6 months.
