Purpose of the Scale

The purpose of this scale is to assess the level of functioning in psychiatric patients, both in inpatient and outpatient settings.

Scale Analysis

The REHB-23 scale was developed by Baker and Hall in 1984 and consists of 23 items, divided into two parts. The first part assesses maladaptive behaviors (e.g., verbal aggression, incoherent speech), while the second part evaluates general functioning (e.g., self-care). The scale is completed by nursing staff based on patient observation over a one-week period.

Scoring and Statistical Analysis

Scoring is based on a range from 5 to 115, with lower scores indicating better patient functioning. The first part (maladaptive behavior) is scored from the sum of 7 items, while the second part (general functioning) is scored from the sum of 16 items.

Validity

Factor analysis indicated satisfactory construct validity.

Reliability

The internal consistency index (Cronbach’s α) for the first part (maladaptive behavior) was low at 0.54, while for the second part (general functioning), it was excellent at 0.92.
