Detection of conscious deception using the Child Abuse Potential Inventory lie scale.

Area of Science:

• Psychological assessment
• Child abuse research
• Measurement validity

Background:

• The Child Abuse Potential Inventory (CAP-Inventory) is a tool used to assess the risk of child abuse.
• Understanding the construct validity of its lie scale is crucial for accurate risk assessment.
• Previous research has not fully established the lie scale's ability to detect response distortion.

Purpose of the Study:

• To evaluate the construct validity of the Child Abuse Potential Inventory lie scale.
• To determine if the lie scale can differentiate between honest responding and intentional response distortion (faking good or faking bad).

Main Methods:

• Two studies were conducted with undergraduate students and parents.
• Participants completed the Child Abuse Potential Inventory, Marlowe-Crowne Social Desirability Scale, or Unlikely Virtues Scale under different response instructions (honest, faking good, faking bad).
• Statistical analyses examined the scales' ability to discriminate between response conditions.

Main Results:

• All tested scales, including the CAP-Inventory lie scale, effectively distinguished honest responses from 'faking good' responses.
• Only the Marlowe-Crowne scale identified 'faking bad' responses through low scores.
• No significant gender differences were found in response distortion across the scales or conditions.

Conclusions:

• The Child Abuse Potential Inventory lie scale demonstrates construct validity in detecting 'faking good' responses.
• Further validation may be needed to reliably detect 'faking bad' responses using the CAP-Inventory lie scale.
• The findings are consistent across student and parent populations, supporting the scale's utility.
