Development and Testing of the Hill‐Bone Compliance to High Blood Pressure Therapy Scale

Abstract

The Hill-Bone Compliance to High Blood Pressure Therapy Scale assesses patient behaviors for three important behavioral domains of high blood pressure treatment: 1) reduced sodium intake; 2) appointment keeping; and 3) medication taking. This scale is comprised of 14 items in three subscales. Each item is a four point Likert type scale. The content validity of the scale was assessed by a relevant literature review and an expert panel, which focused on cultural sensitivity and appropriateness of the instrument for low literacy. Internal consistency reliability and predictive validity of the scale were evaluated using two community based samples of hypertensive adults enrolled in clinical trials of high blood pressure care and control. The standardized alpha for the total scale were 0.74 and 0.84, and the average interitem correlations of the 14 items were 0.18 and 0.28, respectively. The construct and predictive validity of the scale was assessed by factor analysis and by testing of theoretically derived hypotheses regarding whether the scale demonstrated consistent and expected relationships with related variables. In this study, high compliance scale scores predicted significantly lower levels of blood pressure and blood pressure control. Moreover, high compliance scale scores at the baseline were significantly associated with blood pressure control at both baseline and at follow up in the two independent samples. This brief instrument provides a simple method for clinicians in various settings to use to assess patients' self reported compliance levels and to plan appropriate interventions.

Self-report measures of medication adherence behavior: recommendations on optimal use

“…Voils and colleagues [12,52,61] have argued that self-report adherence measures often conflate two distinct constructs-the extent of nonadherence and reasons for nonadherence-and this conflation may be one factor that has limited the psychometric properties and validity of many existing self-report measures. For example, many commonly used self-report measures of medication adherence in hypertension [62][63][64][65][66] are wholly or partially composed of items concerning reasons for missed doses (e.g., due to forgetfulness, side effects, attitudes toward medicines). Voils and colleagues maintained that reasons for nonadherence represent a conceptually distinct antecedent to adherence behavior, and that different measurement models and validation methods are appropriate for each.…”

Home-based interventions for black patients with uncontrolled hypertension: a cluster randomized controlled trial

“…Intensification was defined as either an additional HTN medication or a new class of HTN medication. Patients' self-reported self-management behavior was measured using the Hill-Bone Compliance to High Blood Pressure Therapy scale [20]. This is a 14-item scale comprised of three 4-point subscales measuring reduced sodium intake (three items), appointment keeping (two items) and medication taking (nine items) as reported by the respondent.…”

A theory guided nursing intervention for management of hypertension among adults at rural area

“…It included 6 closedended questions numbered (15)(16)(17)(18)(19)(20) in the tool. These questions developed by Janet (2011) [19] and modified by the researcher: Each correct answer was given 1 point based on predetermined key answer according to the literature, while incorrect answer was given zero.…”

“…-Hill-bone blood pressure medication compliance scale: The Hill-Bone-Scale developed by Kim, Hill, Bone, & Levine, 2000. [20] It was modified by the researcher. It was used to assess patient behaviors for two behavioral domains of hypertension treatment which comprises 10 questions that are summed up to subscales: medication taking (eight items) and appointment keeping (two items).…”
