Introduction

The Four Needs Questionnaire (FNQ-14), also known as the Basic Needs Threat Questionnaire, is a self-report instrument developed by Zadro, Williams, and Richardson (2004) to assess the psychological impact of social exclusion and ostracism. The questionnaire is based on the Four Fundamental Needs Model, which proposes that ostracism threatens four essential psychological needs: belonging, control, self-esteem, and meaningful existence. The FNQ-14 is widely used in social psychology, behavioral research, and studies investigating interpersonal rejection and exclusion experiences.

Description

The FNQ-14 consists of 14 items assessing four fundamental psychological needs affected by social exclusion:

  • Belonging: Feelings of acceptance, connection, and social inclusion.
  • Control: Perceived ability to influence events and interactions.
  • Self-esteem: Feelings of personal value and social worth.
  • Meaningful existence: Feelings of significance and personal importance.

The questionnaire is commonly administered following an exclusion manipulation such as the Cyberball game, a computerized paradigm used to study ostracism experiences.

Responses are rated on a 9-point Likert scale ranging from:

1 = Not at All
to
9 = Very Much So.

Purpose

The FNQ-14 is designed to:

  • Assess immediate psychological reactions to social exclusion.
  • Measure threats to fundamental psychological needs.
  • Examine the emotional consequences of rejection and ostracism.
  • Investigate interpersonal relationships and social belonging.
  • Support research on stigma, rejection sensitivity, and social behavior.

Administration

The questionnaire is self-administered and typically completed immediately after an experimental or real-life exclusion experience. Participants rate their feelings regarding acceptance, control, self-worth, and personal significance during the experience.

The instrument is frequently used with adolescents and adults in laboratory and social psychology research.

Scoring

Items are grouped into four subscales:

  • Belonging.
  • Control.
  • Self-esteem.
  • Meaningful existence.

Scores are calculated by averaging or summing the items within each dimension. Higher scores indicate stronger satisfaction of the respective need, whereas lower scores indicate greater threat or deprivation.

The original study reported acceptable internal consistency coefficients:

  • Belonging: α = .74
  • Control: α = .72
  • Self-esteem: α = .70
  • Meaningful existence: α = .66

Interpretation

Lower FNQ-14 scores indicate that an individual experiences greater psychological threat following exclusion, including feelings of rejection, lack of control, reduced self-worth, and diminished sense of significance.

Higher scores reflect greater psychological security and preservation of fundamental needs after social interaction.

The scale is particularly useful for understanding how social exclusion influences emotional regulation, interpersonal functioning, and psychological well-being.

Statistical Analysis

Psychometric evaluation and research applications commonly include:

  • Descriptive statistics.
  • Internal consistency analysis (Cronbach’s alpha).
  • Factor analysis (EFA/CFA).
  • Correlation analysis.
  • Regression analysis.
  • Mediation and moderation models.
  • Experimental group comparisons (t-test, ANOVA, MANOVA).

Applications

The FNQ-14 is widely used in:

  • Social psychology.
  • Personality psychology.
  • Interpersonal relationship research.
  • Studies of ostracism and rejection.
  • Cyberball experimental research.
  • Mental health and social well-being studies.
  • Research on stigma and social exclusion.

Advantages

  • Strong theoretical foundation based on fundamental psychological needs.
  • Brief and easy to administer.
  • Sensitive to immediate effects of social exclusion.
  • Provides separate assessment of four psychological domains.
  • Widely validated in experimental social psychology.

Limitations

The FNQ-14 primarily assesses short-term perceived threat following exclusion experiences rather than stable personality characteristics. Responses may be influenced by mood, previous social experiences, cultural factors, and the specific exclusion context. Results should be interpreted alongside broader measures of social functioning and psychological adjustment.
