Reliability and first validity of the inner correspondence questionnaire for painting therapy (ICPTh) in a sample of breast cancer patients.

摘要: Abstract Objectives Art therapy (ArT) such as mindfulness-oriented painting is increasingly used in psychosomatic, oncological integrative and rehabilitative medicine. Though it remains unknown how ArT works, we hypothesize that an engaged participation with (‘Inner-Correspondence’) contributes to improved symptom scores. In the context of a comprehensive cohort study for breast cancer survivors cancer-related fatigue, developed patient-reported outcome measure assess ‘Inner Correspondence’ conducted first validation study. Design A 24-item questionnaire on (ICPTh) was administered after ten weeks intervention at six month followup together concurrent scales (Inner Correspondence Peaceful Harmony, Cancer Fatigue Scale, Hospital Anxiety Depression Internal Coherence Scale). Statistical assessment included reliability- factor analyses. Results total n = 68 BC (mean age, 58.2 years, SD = 8.7) participated preliminary Exploratory analysis revealed robust 22-item scale unambiguous four-factor solution explaining 78% variance following subsales: 1) congruence relaxation (11 items), 2) inner development mood (6 3) artistic skill (3 items) 4) task (2 items). The ICPTh yielded high reliability (Cronbach’s alpha = .966, item-total correlation = .497 – .883, test-retest reliability = .888). Conclusions We present reliable instrument therapy. Due small sample size selection further studies are indicated.
