Couple Relationship Education in Australia

The most widely used inventories in Australia are PREmarital Preparation and Relationship Enhancement (PREPARE; Olsen, Fournier, & Druckman, 1996), and the Facilitating Open Couple Communication Understanding and Study (FOCCUS; Markey & Micheletto, 1997). In both PREPARE and FOCCUS, each partner completes a self-report inventory assessing a range of relationship dimensions and isprovided with feedback about that assessment (Larson, Newell, Topham, & Nichols, 2002). In current practice, the feedback sometimes is supplemented with some skill training, though the skill training is not a central part of the inventory approach (Simons & Parker).

There are several important potential strengths in the inventory-based approach to relationship education. First, FOCCUS and PREPARE have both been shown to predict the trajectory of relationship satisfaction in the early years of marriage (Fowers & Olsen, 1986; Larson & Olsen, 1989; Williams & Jurich, 1995). Thus, each inventory assesses factors relevant to relationship outcomes. Second, the inventories provide the opportunity for couples to assess their personal risk and resilience profiles. Third, there is structured training on how to use these inventories (e.g., Olsen, Dyer, & Dyer, 1997). The structured approach to use of the inventories, and the training available, probably at least partially explains the widespread adoption of inventory-based relationship education.

The Value of PREPARE/ENRICH

The value of PREPARE/ENRICH has been demonstrated through research. In 1986 Blaine Fowers and David Olson published a study (Journal of Marital and Family Therapy, 1986, Vol. 12, No. 4, 403-413) designed to determine the predictive validity of PREPARE. This study assessed how helpful PREPARE scores would be in predicting marital success. A 3-year follow-up study was conducted with 164 couples who took PREPARE during their engagement. The authors reported that “…satisfied couples scored significantly higher on the inventory than dissatisfied couples, divorced couples, and couples who cancelled their marriage…Using discriminant analysis, it was found that the PREPARE scores from 3 months before marriage could predict with 80-90% accuracy which couples were separated and divorced from those that were happily married. These findings not only demonstrate the predictive validity of PREPARE, but its potential utility in identifying high-risk couples who could benefit from more intensive premarital counselling.” This finding was repeated in a second study by Andrea Larsen and David Olson published in 1989 (Journal of Marital and Family Therapy, 1989, Vol. 15, No. 3, 311-322). 

In 2000 Luke Knutson and David Olson evaluated the effectiveness of the PREPARE/ENRICH Program (Version 2000) with 100 premarital couples in three groups: the PREPARE Program group (who received an average of four feedback sessions), the PREPARE No Feedback group (who received feedback after the post-test), and the Control group (who received both PREPARE and feedback after the post-test). The PREPARE Program group showed significant positive change, from pre-test to post-test, on marriage expectations, communication, financial management, children and parenting, family and friends, couple closeness, couple flexibility and spiritual beliefs. The PREPARE No Feedback group also showed some significant changes but no significant changes occurred in the Control group.

PREPARE/ENRICH Program: Customised Version (2009) (click here)

The Customized Version of PREPARE/ENRICH is the fifth version and the distinctive features are that it is online and it is tailor made to each couple. It is called the PREPARE/ENRICH Program because it contains both a couple assessment and couple skill building exercises. The program has 10 core scales and over 100 other scales that tap into important aspects of the couple relationship. The goal of the program is to help increase a couples' awareness of their relationship strengths and growth areas and to provide them with skills so that they can improve their relationship.

Olson-Sigg & Olson

The chapter details the two components of PREPARE/ENRICH couple program: the online assessment and the relationship skill-building exercises. While this program is used with dating, engaged, and married couples, the clinical case study is that of a premarital couple. The program is designed so that it can be integrated into most other theoretical and therapeutic models for working with couples.

PREPARE/ENRICH Programs: Research on Couple Types: A Case Study (click here)

This study identified five distinct types of married couples from a sample of 6,267 couples, using the marital inventory ENRICH. Profiles were derived using a three-stage cluster analytic procedure, including an exploratory cluster analysis, a replication of the exploratory results, and a cross-validation. The five-cluster solution was robust. Vitalized couples (12%) reported high relationship quality on all dimensions. Harmonious couples (11%) had relatively high relationship quality. Traditional couples (16%) had scores that were slightly above average with markedly higher scores on parenting and religious scales. Conflicted couples (25%) were characterized by moderately low scores on all but the roles scale. The Devitalized couples (36%) had the lowest scores on every ENRICH dimension.

Research on Effectiveness of the PREPARE/ENRICH Program

PREPARE Outcome Study: Individual vs. Group Feedback - 2011  (click here)

Futris & colleagues

To further advance our understanding of the efficacy of inventory-based premarital education programs, this study examined whether the effects of the PREPARE program varied by delivery format. Following participation in the program, engaged couples exhibited positive gains in knowledge, felt more confident in their relationship, engaged in more positive conflict management behaviors, and felt more satisfied with their relationship. No differences were found between participants who completed a series of conjoint sessions versus a 1-day group workshop. These findings highlight the robustness of premarital education and suggest group workshops can have similar effectiveness as the more prevalent conjoint sessions.

 
 

PREPARE Outcome Study: Feedback vs Only Assessment

Complete Study published in Marriage & Family Journal - 2003 (click here)

Luke Knutson & David H. Olson

This study evaluated the effectiveness of the PREPARE Program (Version 2000) for couples receiving premarital counselling by professionals and clergy trained in the standard 1-day training workshop. There were 153 premarital couples in three groups: the PREPARE Program group (59 couples who received an average of four feedback sessions), the PREPARE No Feedback group (46 couples who received feedback after the post-test), and the Waiting List Control Group (48 couples who received PREPARE and feedback after the post-test).

Results found that only the PREPARE Program group significantly increased their couple satisfaction, while there was no change in the PREPARE No Feedback or the Waiting List Control groups. Couples in the PREPARE Program improved in 10 out of 13 relationship categories, while those in the PREPARE No Feedback group increased in 4 of the 13 categories.

Significant changes were made in the couple types only in the PREPARE Program group, demonstrating a significant impact on 90% of these couples. In the PREPARE Program group, the number of Vitalized couples (the most satisfied type) increased by 52% from pre to post-test. Over half (55%) of the three other couple types (Harmonious, Traditional, and Conflicted) increased one or more levels. For the highest risk couples, the Conflicted types, 83% moved to a more positive couple type.

PREPARE/ENRICH and Couple Communication Program - 2007 (click here)

David H. Olson & Sherod Miller

This longitudinal study followed up on 25 married couples one to five years after marriage who had taken both the PREPARE/ENRICH and the Couple Communication programs before marriage. Overall, the results demonstrated the couples were very satisfied with both programs and also found the combination of two programs very valuable. The couples significantly improved their communication, conflict resolution skills and marital satisfaction. Couples reported they found it helpful to their marriage to coach other couples on communication skills.
