Abstract
The Spouse Sobriety Influence Inventory (SSII) is a comprehensive psychological scale designed to measure the frequency and type of influence strategies used by spouses of individuals struggling with alcohol abuse. Developed by Thomas, Yoshioka, and Ager in 1993, the inventory consists of 52 items that capture a wide range of behaviors—from positive support and encouragement to confrontational, controlling, or negative actions—employed by the spouse over the preceding six months to affect the drinker’s behavior. The SSII is vital for research and clinical settings focused on understanding the dynamics of marital relationships affected by addiction and for developing targeted interventions for co-dependent behaviors or enabling patterns.

Purpose
The primary purpose of the Spouse Sobriety Influence Inventory (SSII) is to systematically quantify the various control and influence efforts exerted by a non-drinking or less-drinking spouse on their partner who abuses alcohol. The instrument was developed to move beyond generalized concepts of “enabling” or “co-dependence” by providing specific, observable behaviors related to influencing sobriety or reducing drinking frequency.
By assessing both supportive and controlling/punitive actions, the SSII allows clinicians and researchers to categorize and analyze the efficacy of different spousal intervention strategies. This detailed assessment is crucial for tailoring therapeutic approaches, particularly those involving couples therapy or family systems interventions for alcohol use disorders.
Construct
The SSII measures the construct of Spousal Influence Strategies regarding alcohol use. This construct is generally divided into two empirically derived sub-constructs:
- Sobriety Support (SSS): Measures positive and constructive strategies aimed at encouraging abstinence or reduction in drinking, such as praising sobriety, suggesting non-alcoholic activities, or seeking professional help for oneself.
- Drink Control (DCS): Measures negative, confrontational, manipulative, or avoidance strategies aimed at stopping or controlling the drinking, such as hiding alcohol, making threats, arguing, or expressing disapproval.
The scale assumes that a spouse’s actions are not monolithic but represent a complex mixture of behaviors, some of which may be helpful in promoting sobriety, while others may exacerbate conflict or lead to negative relationship outcomes.
Validity
The SSII exhibits strong content validity, as the items were derived from extensive observation and clinical interviews regarding spousal interactions in the context of alcohol abuse. Its construct validity is supported by the clear differentiation of items into the two primary subscales (SSS and DCS), reflecting distinct behavioral domains that align with therapeutic models of intervention (e.g., positive reinforcement versus punishment or coercion).
Studies utilizing the SSII, such as those by Thomas, Yoshioka, & Ager (1996), have demonstrated that the subscales predict different outcomes in the drinker’s behavior and the overall quality of the marital relationship, confirming its utility in assessing the complex role of the spouse in the recovery process. The scale provides a behavioral index that is more objective than general self-reports of distress or enabling.
Reliability
The reliability of the SSII is typically assessed through internal consistency measures for its two main subscales. Research indicates that both the Sobriety Support Scale (SSS) and the Drink Control Scale (DCS) possess acceptable to good internal consistency (often measured using Cronbach’s alpha), suggesting that the items within each subscale reliably measure their intended construct. The large number of items (52 total) contributes to the overall stability and comprehensiveness of the instrument.
Factor Analysis
A central finding supporting the structure of the SSII is the clear differentiation achieved through factor analysis. The 52 items were consistently found to load onto two primary, distinct factors, leading to the creation of the two subscales:
- Sobriety Support Scale (SSS): This subscale comprises 7 items (Items 13, 15, 16, 20, 28, 29, and 31). These items capture positive, proactive, and encouraging actions.
- Drink Control Scale (DCS): This subscale comprises the remaining 45 items. These items cover confrontational, negative, restrictive, or avoidant behaviors, including both verbal expressions of disapproval and physical actions (e.g., hiding alcohol or money).
This two-factor structure underscores the conceptual distinction between supportive influence and coercive control efforts made by the spouse.
Instrument
Test Type: Self-report Inventory/Behavioral Frequency Scale
Format: 52 items rated on a 5-point Likert scale based on frequency of occurrence over the past six months.
Language Available: English (Original)
Population Group: Spouses or partners of individuals with alcohol use disorder.
Age Group: Adults (Typically 18+)
Population Details: Individuals in committed relationships (married or cohabiting) with a partner identified as an alcohol abuser or dependent drinker.
Test Methodology: Respondents indicate the frequency of their specific influence behaviors using the following response options: 1 = Always, 2 = Frequently, 3 = Occasionally, 4 = Rarely, 5 = Never. Scoring typically involves summing item responses within the SSS and DCS subscales, often after reversing negative items, though the specific scoring protocol depends on the research application.
