Description

The Interpersonal Support Evaluation List (ISEL-12) is a standardized psychometric instrument designed to assess perceived social support, evaluating the extent to which individuals believe that supportive interpersonal resources are available when needed. As the brief version of the original Interpersonal Support Evaluation List, the ISEL-12 provides a concise yet scientifically robust assessment of perceived social support, making it suitable for both clinical practice and large-scale epidemiological and psychosocial research.

Perceived social support is recognized as one of the most important protective psychosocial factors influencing psychological resilience, stress management, emotional adjustment, and overall health. Unlike objective measures of social network size, the ISEL-12 evaluates individuals’ subjective perception of available support, which has consistently demonstrated stronger associations with mental health, physical health, quality of life, and adaptive coping.

The questionnaire consists of 12 self-report items organized into three complementary dimensions of social support. Appraisal Support evaluates the perceived availability of trusted individuals who can provide advice, guidance, and constructive feedback during difficult situations. Belonging Support assesses the extent to which individuals perceive themselves as part of a supportive social network with opportunities for companionship and shared activities. Tangible Support measures the perceived availability of practical assistance and material help when needed. Participants indicate their level of agreement with each statement using a Likert-type response scale, ranging from “Strongly Agree” to “Strongly Disagree.”

The Interpersonal Support Evaluation List (ISEL-12) is widely applied in clinical psychology, health psychology, psychiatry, public health, nursing, social work, behavioral medicine, epidemiology, rehabilitation, community psychology, and quality-of-life research, where it serves as one of the most widely recognized brief instruments for evaluating perceived social support.

Data Analysis and Use

Data obtained from the Interpersonal Support Evaluation List (ISEL-12) are analyzed using comprehensive psychometric and statistical procedures designed to evaluate individuals’ perceptions of available social support. Individual responses are summed according to the standardized scoring protocol to calculate separate scores for Appraisal Support, Belonging Support, and Tangible Support, together with an overall Perceived Social Support Score.

Psychometric evaluation typically includes analyses of internal consistency using Cronbach’s alpha coefficient, together with assessments of test–retest reliability, construct validity, content validity, criterion validity, convergent validity, discriminant validity, and confirmatory factor analysis (CFA) to verify the three-factor structure of the instrument. Cross-cultural validation, measurement invariance analyses, and comparisons with other established social support measures are frequently performed to ensure the reliability and generalizability of the questionnaire across diverse populations.

Statistical analyses commonly include descriptive statistics, calculation of means and standard deviations, Pearson or Spearman correlation analyses, multiple regression models, structural equation modeling (SEM), mediation and moderation analyses, cluster analysis, and comparative procedures such as independent-samples t-tests and analysis of variance (ANOVA). The ISEL-12 is frequently used to investigate relationships between perceived social support and variables including anxiety, depression, stress, resilience, coping strategies, psychological well-being, life satisfaction, physical health, and overall quality of life. The questionnaire is also valuable for monitoring changes in perceived social support following psychosocial interventions or significant life events.

The findings are particularly valuable for psychologists, psychiatrists, physicians, nurses, social workers, public health professionals, and researchers seeking to identify psychosocial protective factors, evaluate intervention effectiveness, monitor changes in social support over time, and develop evidence-based programs that strengthen interpersonal relationships and psychological resilience.

Objective

The primary objective of the Interpersonal Support Evaluation List (ISEL-12) is to provide a reliable, valid, and efficient assessment of perceived social support across diverse populations. The questionnaire enables researchers and healthcare professionals to evaluate the availability of emotional, informational, and practical support while examining the role of social support in promoting psychological well-being, resilience, and overall health.

The instrument supports both scientific research and clinical practice by facilitating psychosocial assessment, identifying individuals with limited perceived support, evaluating intervention outcomes, and contributing to evidence-based prevention and treatment strategies aimed at enhancing social connectedness, emotional well-being, and quality of life.

Scoring

The Interpersonal Support Evaluation List (ISEL-12) consists of 12 self-report items, with participants responding to each statement using a Likert-type response scale ranging from “Strongly Agree” to “Strongly Disagree.” Individual responses are scored according to the standardized scoring protocol to calculate separate scores for Appraisal Support, Belonging Support, and Tangible Support, together with an overall Perceived Social Support Score.

Higher scores indicate greater perceived availability of social support, stronger interpersonal relationships, greater access to practical assistance and emotional guidance, and increased psychological resources for coping with stressful situations. Lower scores suggest more limited perceived support, weaker social integration, and potentially greater vulnerability to stress, emotional distress, and reduced psychological well-being.

Interpretation of questionnaire scores should always be supported by comprehensive psychometric evaluation, including analyses of Cronbach’s alpha coefficients, construct validity, criterion validity, confirmatory factor analysis, measurement invariance, normative comparisons, and cross-cultural validation, ensuring accurate and reliable assessment across diverse populations.
