Psychometric properties of a Spanish-language version of the Short Inventory of Problems.

Abstract

Hispanic Americans are substantially under-represented in clinical and research samples for substance use treatment, with language cited as one of the major barriers to their participation, indicating a need for more validated assessments in Spanish. This study evaluated the psychometric properties of a Spanish version of the Short Inventory of Problems (SIP), used in a multisite, randomized trial conducted for Spanish-speaking substance users. The sample included 405 Spanish-speaking treatment seekers, mostly male (88%) and legally mandated to treatment (71%). The Spanish version of the revised SIP (SIP-RS), as well as other commonly-used assessment measures translated into Spanish, were administered at baseline and at the end of treatment. Internal consistency was excellent (α = .96), and construct validity was supported through correlations with composite scores from the Addiction Severity Index (ASI) (e.g., r = .57, p<.01 for ASI drug composite), and through differential SIP-RS scores according to diagnostic criteria. The SIP-RS also demonstrated an association with substance use and treatment retention, with higher baseline scores associated with significantly less abstinence during treatment (β = −.22, p<.01) and fewer days retained in treatment (β = −.14, p<.05). However, the latter association was moderated by participants’ legal status. Nevertheless, this Spanish-translated version of the SIP (SIP-RS) appears to be a reliable and valid assessment of adverse consequences associated with alcohol and drug use, with psychometric properties comparable to the English version.

Characteristics of a Treatment-Seeking Population in Outpatient Addiction Treatment Centers in Mexico

“…This measure assesses the patient's perception of adverse consequences of his/her substance use in a period of 3 months prior to the assessment date. This scale has a good internal consistency (alpha = 0.96) and showed to have construct validity through correlations with scores from the ASI (Kiluk et al, 2013). Scores higher than mean for each negative consequence were classified as "problem" in this study.…”

Latent Impulsivity Subtypes in Substance Use Disorders and Interactions with Internalizing and Externalizing Co-Occurring Disorders

“…A five-factor model with a version of the SIP-R ( 28 ) showed acceptable goodness-of-fit (χ 2 = 708.03; df = 85; CFI = 94; RMSEA = 0.09). For this study, we used a Spanish-language version adapted in Hispanic Americans ( 29 ). This variable was also used as a measure of severity of substance use in the main analysis.…”

Co-Occurring Disorders: A Challenge for Mexican Community-Based Residential Care Facilities for Substance Use

“…The SIP-R is a 17-item self-report scale that assesses the frequency of negative consequences of drug and alcohol use in the past three months through a 4-point Likert scale that ranges from “never” to “almost daily.” In addition to a total score, the SIP-R also produces five sub-scale scores (interpersonal, intrapersonal, physical, impulse control and social). Its psychometric properties are reported elsewhere (Kiluk et al, 2013).…”
