Internet-based Intervention for Enhancing the Psychological Well-being of Elderly Caregivers

COPE is an assessment of carers' perceptions of their role as caregiver: negative impact, positive value and quality of support of caregiving in informal carers of older people. It was developed in collaboration with several European countries as a brief first-stage assessment tool to identify caregivers who may need supportive interventions of any kind.

The WHOQOL-BREF instrument comprises 26 items, which measure the following broad domains: physical health, psychological health, social relationships, and environment. The WHOQOL-BREF is a shorter version of the original instrument that may be more convenient for use in large research studies or clinical trials.

Generalized Anxiety Disorder 7 (GAD-7) is a self-reported questionnaire for screening and severity measuring of the four most common anxiety disorders (Generalized Anxiety Disorder, Panic Disorder, Social Phobia and Post Traumatic Stress Disorder). GAD-7 has seven items, which measure severity of various signs of GAD according to reported response categories with assigned points (Not at all: 0 points; Several days: 1 point; More than half the days: 2 points; and Nearly every day: 3 points). Assessment is indicated by the total score (min 0, max 21). Higher GAD-7 scores correlate with disability and functional impairment. 5-9 points indicate moderate anxiety, 10-14 moderate and >15 severe anxiety.

The SOC-13 is derived from the original 29-item scale measuring different aspects of sense coherence. Responses are made on a 7-point scale.The SOC-13 scale has three components: Comprehensibility (items 2, 6, 8, 9, 11; min 5, max 35), Manageability (items 3, 5, 10, 13; min 4, max 28) and Meaningfulness (items 1, 4, 7, 12; min 4, max 28) with higher scores indicating better outcomes. This scale is rated on a 7-point likert scale, a total score can also be used and the coding for items 1, 2, 3, 7 and 10 should be reversed. The subscales are combined to compute a total score. SOC scores range from 13 to 91 with higher scores indicating a better outcome: more sense of coherence.

The AAQ-II is a measure with seven questions to be answered on a scale of 1 (never true) to 7 (always true) participant's willingness to be in contact with negative private events, acceptance of these events, and whether they can live in accordance with their values. Summation of the scores results in a total mark ranging from 7 to 49, whereby a higher score indicates means a higher level of psychological flexibility, e.g. higher acceptance.

The EACQ is a scale measuring experiential avoidance in the caregiving context: 1. Active Avoidant Behaviors, 2) Intolerance of Negative Thoughts and Emotions Towards the Relative and 3) Apprehension Concerning Negative Internal Experiences Related to Caregiving. The questionnaire consists of 15 items rated on a 5-point Likert scale. Each statement can be answered by 1: not at all, 2: a little, 3: somewhat, 4: often and 5: a lot. Factor 1 is made up of 6 items that measure caregivers' behaviors for avoiding negative thoughts related to caregiving (min 5, max 25). Factor 2 include 4 items with content related to rigid verbal thinking about negative emotions/thoughts with regard to the care-recipient (min 4, max 20), the factor 3 composes of 5 items referring to reluctant attitudes towards negative thoughts regarding the relative (min 5, max 25). The subscales are summed to compute a total score. Higher values represent more avoidance, e.g. worse outcome.

The WBSI is a 15-item questionnaire that is designed to measure thought suppression. Chronic thoughts suppression is related to obsessive thinking and negative affect associated with depression and anxiety. The scoring of the WBSI is based on a 5 point scale from Strongly disagree (1) to Strongly agree (5). The total score (range from 15 to 75) is obtained by summing up the responses that are provided by respondents. Higher scores on the WBSI indicate greater tendencies to suppress thoughts.

The Short Five personality questionnaire is a 60-item questionnaire constructed for measuring 30 facets of the Five-Factor Model

The Short Physical Performance Battery (SPPB) is a group of measures that combines the results of the gait speed, chair stand and balance tests (Guralnik et al., 2000). It has been used as a predictive tool for possible disability and can aid in the monitoring of function in older people. The scores range from 0 (worst performance) to 12 (best performance). The SPPB has been shown to have predictive validity showing a gradient of risk for mortality, nursing home admission, and disability.
