mental disorder, and no additional inclusion criteria were applied. Participants were recruited
and included in the study between June 1 and August 30, 2024. A non-probability
convenience sampling method was employed, based on the accessibility and willingness of
older adults residing in Cuenca to participate in the study.
Instruments
The APGAR is a 5-item scale that assesses the user's perception of their satisfaction with
family support, analysing basic functions such as adaptation, participation, gradient of
resources, affection and problem-solving capacity, present in all families according to their
structure, development, integration or demographics. The response options of the items of
the scale determine degrees of frequency of certain dynamics, these are: "never", indicating
that the evaluated aspect never occurred in the family; "almost never", indicating that it
happened very rarely; "sometimes", indicating that it happened on some occasion; "almost
always", indicating that it occurred frequently and "always", indicating that the evaluated
aspect always occurred in the family. Each question is scored using a Lickert scale on values
of 0-2, where answers such as "never" and "almost never", receive 0 points; "sometimes"
they receive 1 point; "almost always" and "always" receive 2 points, obtaining a quantitative
index of 0 - 10 at the end. Three cut-off point scales are considered: a) normal function (7-
10 points), b) moderate dysfunction (4-6 points), and c) severe dysfunction (0-3 points).
An ad hoc survey was applied with sociodemographic variables (age, marital status,
educational level, ethnic self-perception, economic income in the last month, way of
obtaining income and socioeconomic level).
Procedure
Researchers visited 1009 homes in Cuenca, providing a brief description of the study
objectives, procedures, confidentiality measures, and the voluntary nature of participation.
Participants signed informed consent to confirm their understanding and willingness to
participate.
The questionnaire was administered at home, allowing participants to complete it at their
convenience. No identifiable information (e.g., names) was collected to ensure privacy.
Responses were securely stored in an encrypted database accessible only to the principal
investigator, adhering to data protection regulations.
Analyses
Psychometric properties of the APGAR-family scale were assessed in three stages. Internal
consistency was evaluated to determine the reliability of the items and the overall scale, with
reliability benchmarks interpreted as follows: ≥.70 acceptable, ≥.80 good, and ≥.90 excellent.
