Picture of (PIY) Personality Inventory for Youth


The PIY is a multidimensional, psychometrically sound self-report instrument designed specifically for young people. It is composed of 270 items covering 9 nonoverlapping clinical scales and 24 nonoverlapping subscales:

Cognitive Impairment

  • Poor Achievement and Memory
  • Inadequate Abilities
  • Learning Problems


  • Brashness
  • Distractibility and Overactivity
  • Impulsivity


  • Antisocial Behavior
  • Dyscontrol
  • Noncompliance

Family Dysfunction

  • Parent-Child Conflict
  • Parent Maladjustment
  • Marital Discord

Reality Distortion

  • Feelings of Alienation
  • Hallucinations and Delusions

Somatic Concern

  • Psychosomatic Syndrome
  • Muscular Tension and Anxiety
  • Preoccupation With Disease

Psychological Discomfort

  • Fear and Worry
  • Depression
  • Sleep Disturbance

Social Withdrawal

  • Social Introversion
  • Isolation

Social Skill Deficits

  • Limited Peer Status
  • Conflict With Peers

The 24 subscales reveal more specific clinical content, making the PIY an excellent diagnostic tool. In addition, four validity scales tell you whether the respondent is exaggerating, malingering, or responding defensively, carelessly, or without adequate comprehension. The first 80 items of the test can be used as a screener to quickly identify students who would show problems on the full inventory.

Items are written at a third-grade reading level. An audio CD is available for poor readers, and a Spanish Administration Booklet is available for those who read Spanish only.

The PIY gives you a reliable and valid measure of child and adolescent psychopathology, based on the respondent’s own perceptions.
