Interscorer reliability for the Hand Test administered to children.

Area of Science:

• Psychological assessment
• Child psychology
• Personality testing

Background:

• The Hand Test is a projective measure used to assess personality.
• Its utility in assessing children's personalities requires further validation.
• Interscorer reliability is crucial for the consistent application of psychological tests.

Purpose of the Study:

• To assess the utility of the Hand Test as a quick and reliable personality measure for 100 children.
• To estimate the interscorer reliability of the Hand Test using intraclass correlations and Kappa coefficients.
• To identify potential areas for improving the Hand Test's reliability in child assessments.

Main Methods:

• The Hand Test was administered to 100 children.
• Interscorer reliability was calculated using intraclass correlations and Kappa coefficients.
• Scorers underwent training prior to data collection.

Main Results:

• Satisfactory intraclass correlations were achieved for quantitative scores (20/22 > .70) and qualitative scores (12/27 > .70) after training.
• Kappa coefficients were generally lower than intraclass correlations.
• Lower reliability for qualitative scores may be linked to scorer memory overload and low response frequency.

Conclusions:

• The Hand Test demonstrates acceptable reliability for quantitative scores in children, comparable to other projective tests.
• Modifications to administration directions for young children and clearer scoring rules are recommended.
• Further research is needed to enhance the reliability of qualitative scores for child personality assessment.
