Fear of physical activity (FoPA) has been suggested as a psychological barrier to exercise-based cardiac rehabilitation and everyday physical activity (PA) in patients with heart failure (HF). We evaluated the recently developed Fear of Activity in Situations-Heart Failure (FActS-HF) questionnaire that assesses affective/cognitive fear reactions to situations of varying PA intensities.
The FActS-HF was given to 132 ambulatory patients with stable HF (67 ± 12 years, 80% men). In 121 participants with valid FActS-HF data, the questionnaire's dimensionality was investigated. Psychometric properties were determined in terms of reliability and validity. We assessed convergent and discriminant correlations of FoPA with anxiety, kinesiophobia, and depression. External validation criteria encompassed clinical variables and objectively assessed accelerometer measures of everyday PA in a subsample of 61 participants.
The FActS-HF measures a unidimensional construct (i.e., FoPA) based on items presenting varying PA intensities (i.e., the more intense the PA, the stronger the fear response). The scale demonstrated good 2-week stability (r = 0.82) and excellent internal consistency reliability (α = 0.97). FoPA was moderately to strongly associated with anxiety and kinesiophobia, and weakly to moderately associated with state/trait depression, supporting convergent and discriminant validity, respectively. High FoPA was associated with feeling uninformed about HF, comorbidities, non participitation to cardio fitness groups, and less stair climbing, as measured by accelerometry.
The FActS-HF is a reliable and valid instrument to measure FoPA in patients with HF and provides a promising tool for further research and practice.
对体力活动的恐惧（FoPA）被认为是心力衰竭（HF）患者进行运动心脏康复及日常体力活动（PA）的心理障碍。我们评估了最近开发的心力衰竭情境下活动恐惧（FActS-HF）问卷，该问卷用于评估对不同PA强度情境的情感/认知恐惧反应。
FActS-HF问卷被发放给132例病情稳定的门诊HF患者（67±12岁，80%为男性）。在121例有有效FActS-HF数据的参与者中，对问卷的维度进行了研究。从信度和效度方面确定了心理测量学特性。我们评估了FoPA与焦虑、运动恐惧及抑郁的聚合效度和区分效度。外部验证标准包括临床变量以及在61例参与者的子样本中通过客观评估加速度计测量的日常PA。
FActS-HF基于呈现不同PA强度的项目测量一个单维结构（即FoPA）（即PA强度越高，恐惧反应越强）。该量表显示出良好的2周稳定性（r = 0.82）和出色的内部一致性信度（α = 0.97）。FoPA与焦虑和运动恐惧呈中度至高度相关，与状态/特质抑郁呈低度至中度相关，分别支持聚合效度和区分效度。通过加速度计测量，高FoPA与对HF、合并症了解不足、未参加心脏健康组以及爬楼梯较少有关。
FActS-HF是测量HF患者FoPA的可靠且有效的工具，为进一步研究和实践提供了一个有前景的工具。
