Family Distress Index (FDI-8)

Introduction

The Family Distress Index (FDI-8) is a brief self-report instrument designed to assess the level of distress experienced within the family environment. The questionnaire measures emotional strain, interpersonal conflict, and difficulties in family functioning, providing a practical tool for identifying families who may benefit from psychological or social support.

Description

The FDI-8 consists of eight items that evaluate key aspects of family distress, including:

  • Emotional strain.
  • Family conflict.
  • Relationship difficulties.
  • Family functioning.
  • Daily stress within the family.

Items are typically rated using a Likert-type scale, with higher scores indicating greater levels of perceived family distress.

Purpose

The FDI-8 is designed to:

  • Assess family distress.
  • Identify areas requiring intervention.
  • Support clinical and family assessments.
  • Monitor changes following intervention.
  • Facilitate research on family functioning and well-being.

Administration

The questionnaire is completed by family members and requires only a few minutes to administer. Standardized administration procedures are recommended to ensure reliable results.

Scoring

Each item is scored according to the response scale, and item scores are summed to obtain a total score. Higher total scores indicate greater family distress.

Interpretation

Higher FDI-8 scores suggest increased emotional burden, family conflict, and difficulties in family functioning. Results should be interpreted alongside clinical interviews and complementary measures of family relationships and psychological well-being.

Statistical Analysis

Common psychometric analyses include:

  • Descriptive statistics.
  • Internal consistency (Cronbach’s alpha).
  • Exploratory and Confirmatory Factor Analysis (EFA/CFA).
  • Correlation and regression analyses.
  • Group comparisons and validity assessment.

Applications

The FDI-8 is commonly used in:

  • Family psychology.
  • Clinical psychology.
  • Counseling services.
  • Social work.
  • Family intervention and outcome research.

Advantages

  • Brief and easy to administer.
  • Suitable for clinical and research settings.
  • Useful for screening family distress.
  • Appropriate for monitoring intervention outcomes.

Limitations

As a self-report instrument, responses may be influenced by individual perceptions, emotional state, and family circumstances. The FDI-8 should be interpreted together with other clinical and psychosocial assessment tools.
