About

This study evaluated the efficacy of HypnoDiaCare, a two-session integrative intervention that combines clinical hypnosis with diabetes self-management education based on the AADE7 Self-Care Behaviors framework, for adults with type 2 diabetes mellitus (T2DM). The trial used a three-arm randomized controlled design with HypnoDiaCare, EduDiaCare (education-only), and a neutral visual attention control group. All participants completed two individual sessions over a 1-2-week interval and completed pretest and posttest assessments.

HypnoDiaCare integrates hypnotic induction, guided imagery, ego strengthening, and positive suggestions with diabetes self-management principles. EduDiaCare provides structured education without hypnosis, and the control group viewed neutral images designed to maintain stable emotional and physiological states.

After the initial posttest, control-group participants were re-randomized to receive HypnoDiaCare or EduDiaCare to explore delayed-intervention effects. Primary outcomes were diabetes self-management and quality of life, while secondary outcomes included psychological symptoms and affective states.

The study aims to determine whether HypnoDiaCare produces greater improvements in self-management and quality of life compared with education-only and attention-control conditions.

Full description

This study is a three-arm, pretest-posttest, single-blind randomized controlled trial designed to examine the efficacy of HypnoDiaCare, an integrative intervention combining clinical hypnosis techniques with diabetes self-management education for adults with type 2 diabetes mellitus (T2DM). The trial compared HypnoDiaCare with two comparator conditions: (1) EduDiaCare, a structured education-only program based on the AADE7 Self-Care Behaviors framework, and (2) a neutral visual attention control condition.

Participants were recruited through community health centers (Puskesmas) and social media platforms from December 2024 to March 2025. Eligible participants were adults aged 20 years or older with a documented or self-reported diagnosis of T2DM, able to read Indonesian, and not currently undergoing psychological therapy or experiencing severe psychiatric conditions. All participants provided written informed consent.

Randomization was conducted individually using simple randomization procedures. The study employed a single-blind design in which participants were unaware of the specific nature of the intervention they received. Interventions were delivered individually by trained clinical psychologists following standardized manuals to ensure protocol fidelity.

The HypnoDiaCare intervention consisted of two sessions: a 90-120-minute first session and a 60-minute second session. The structure followed established stages of clinical hypnosis, including induction, deepening, therapeutic imagery, ego strengthening, and post-hypnotic suggestions. Diabetes self-management principles were embedded within the therapeutic suggestion phases. EduDiaCare comprised two 60-minute sessions of individualized diabetes self-management education covering healthy eating, physical activity, medication adherence, glucose monitoring, emotional coping, problem solving, and decision making. The control group received two sessions of neutral visual exposure using standardized affectively neutral images designed to control for attention and expectancy effects.

Primary outcomes were diabetes self-management, assessed using the Indonesian version of the Diabetes Self-Management Instrument (IDN-DSMI), and quality of life measured using the WHOQOL-BREF. Secondary outcomes included depression, anxiety, and stress (DASS-42), as well as affective states measured by the Positive and Negative Affect Schedule - Expanded Form (PANAS-X). Assessments were completed at baseline (pretest) and after the second session (posttest 1). Participants in the control group who later received HypnoDiaCare or EduDiaCare underwent additional pre- and post-intervention assessments for exploratory analysis.

No investigational drugs or devices were used. The study received ethical approval from the Ethics Committee of the Faculty of Psychology, Universitas Gadjah Mada. All procedures were conducted in accordance with ethical standards for research involving human participants.
