Family Assessment Device (FAD)
Also known as: FAD, McMaster Family Assessment Device
The Family Assessment Device is a widely used self-report instrument designed to measure family functioning across six key domains derived from the McMaster Model of Family Functioning. Developed by Epstein, Baldwin, and Bishop in 1983, the FAD assesses problem-solving, communication, roles, affective responsiveness, affective involvement, and behavioral control in families. It is used extensively in family therapy research, clinical assessment of family dynamics, and as an outcome measure in family-based interventions for mental health, medical, and developmental conditions.

When to use it
The FAD is appropriate for families seeking family therapy, family assessment prior to individual treatment, and families managing medical or psychiatric illness. It is valuable in research examining family functioning as a predictor of individual psychopathology, treatment outcomes, or quality of life. The instrument is useful for tracking family change during therapy. It is NOT designed to assess child maltreatment or safety risk; these require separate evaluation.
Strengths & limitations
- Grounded in a well-established theoretical model (McMaster) that has influenced family therapy practice globally.
- Comprehensive assessment of multiple family domains (6 subscales plus general functioning); enables differentiated intervention targets.
- Strong psychometric properties across diverse samples; Cronbach α = 0.72–0.84 for subscales.
- Widely translated and validated in 20+ languages and culturally diverse samples; normative data available for multiple populations.
- Vulnerable to social desirability bias and family collusion (family members agreeing to present a united façade); perceptions may not reflect observed behavior.
- Limited applicability for children under 12; a separate child version (FAD-C) is needed.
- Does not assess abuse, violence, or safety concerns directly; must be supplemented with specific safety assessment.
- Subscale correlations are moderate to high (0.60–0.80), suggesting some construct overlap; subscale scores should not be interpreted in strict isolation.
Frequently asked
What if family members' FAD scores disagree strongly (e.g., one member rates communication as good, another as poor)?
Discrepancies are common and clinically informative. They suggest that family members perceive family dynamics differently, which itself may be a problem. Large disagreements warrant clinical exploration: one member may feel unheard, power imbalances may exist, or family members may have different expectations about communication. The discrepancy itself is a treatment focus.
Is the FAD appropriate for blended families or single-parent households?
Yes. The FAD is applicable to diverse family structures, including blended families, single-parent households, and multigenerational families. The scale assesses functional processes (communication, problem-solving) that apply across family types. However, normative data and interpretation guidelines may differ for non-traditional family structures; clinicians should consider cultural context and family-specific norms.
Can the FAD be used to identify child maltreatment?
No. While high FAD scores may indicate problematic family functioning that increases maltreatment risk, the FAD does not directly assess abuse, violence, or safety. Families with child maltreatment require separate assessment using instruments designed for abuse screening (e.g., Parent-Child Conflict Tactics Scale) and clinical interviews with a trained evaluator. Never rely on the FAD alone for safety assessment.
How do I interpret FAD results for a family from a different cultural background?
Cultural norms for family communication, emotion expression, roles, and behavioral control vary significantly. For example, some cultures emphasize parental authority over democratic decision-making; others prioritize emotional restraint. When interpreting FAD scores for culturally diverse families, consider culture-specific norms and, ideally, use culture-adapted normative cutoffs if available. Discuss results with the family to clarify whether low scores reflect true dysfunction or cultural differences.
What is the difference between the FAD and the FAD-C (child version)?
The FAD is designed for adolescents (age 12+) and adults. The FAD-C is a shortened version adapted for younger children (ages 8–12) with simpler language. If you are assessing families with children under 12, use the FAD-C for those children and the standard FAD for older family members. Families can thus be assessed with mixed versions if they span multiple age groups.
