چکیده:
Objective: This study aimed to evaluate the psychometric properties and the factor structure of
the Behavior Problems Inventory (BPI-01) among students with intellectual disabilities in Iran.
Methods: The Persian version of BPI-01 was administered to the care staff of Iranian children
and adolescents (n=591) who had been detected as suffering from intellectual disabilities.
Iranian children and adolescents with intellectual disabilities in the present study lived in one
of the 4 provinces of Tehran, Esfahan, Karaj, and Kurdistan. Cronbach α and confirmatory
factor analysis (CFA) were used for analyzing the data.
Results: The results of the study showed that the scale could reach an acceptable level of
internal consistency (Cronbach α ranged from 0.83 to 0.94). Furthermore, CFA supported the
unidimensionality of the subscales as well as 3 factor structure proposed in the original BPI-01.
Conclusion: The Persian version of BPI-01 enjoys an acceptable level of reliability and is
explained by the same factor structure proposed in the original BPI-01. The limitations and
some applications of the present study will be discussed too.

Good examples of such broad band instruments are Aberrant Behav- ior Checklist (ABC; Aman, Singh, Stewart, & Field, 1985a, 1985b, 1995), Developmental Behavior Check- list (DBC; Einfeld & Tonge, 2002), and Nisonger Child Behavior Rating Form (NCBRF; Aman, Tassé, Rojahn, & Hammer 1996).
, 2001; Rojahn, Wilkins, Matson, & Boisjoli, 2010; Van Ingen, Moore, Zaja, & Rojahn, 2010) reveals that the overall internal consis- tency of BPI-01 is acceptable, however, the internal con- sistency of three subscales varies, with the self-injurious behavior scale generally evaluated to have the lowest consistency among the subscales.
The present study aimed to evaluate the psychometric properties and the factor structure of the Iranian version of BPI-01, based on data from Iranian students who had been detected as suffering from intellectual disabilities.
BPI-01 is a 49-item informant-based rating scale for behavior problems in individuals with IDs. It has 3 subscales that have been validated by CFA and found to be reasonably reliable (Rojahn et al.
Means, corrected item total correlations, and factor loadings of the Behavior Problems Inventory (BPI-01), frequency and severity scores.
In summary, a strong claim can be put forward that the Persian version of BPI-01 is a valid and reliable measure for the evaluation of behavioral problems (self-injurious behavior, stereotyped behavior, and aggressive/destructive behavior) among students with intellectual disabilities in Iran."
