Validating the German Version of the Quality of Relationship Inventory: Confirming the Three-Factor Structure and Report of Psychometric Properties

Abstract

Research on psychosocial influences such as relationship characteristics has received increased attention in the clinical as well as social-psychological field. Several studies demonstrated that the quality of relationships, in particular with respect to the perceived support within intimate relationships, profoundly affects individuals' mental and physical health. There is, however, a limited choice of valid and internationally known assessments of relationship quality in Germany. We report the validation of the German version of the Quality of Relationships Inventory (QRI). First, we evaluated its factor structure in a representative German sample of 1.494 participants by means of confirmatory factor analysis. Our findings support the previously proposed three-factor structure. Second, importance and satisfaction with different relationship domains (family/children and relationship/sexuality) were linked with the QRI scales, demonstrating high construct validity. Finally, we report sex and age differences regarding the perceived relationship support, conflict and depth in our German sample. In conclusion, the QRI is a reliable and valid measurement to assess social support in romantic relationships in the German population.

The Factorial Structure of the Quality of Relationships Inventory-Parents Perception (QRI-PP)

“…It should also be noted that this study did not meet the results obtained in other studies carried out previously, that found a tri-factorial structure that matches the original version: in Portuguese context, studies of Neves (2006), Marques et al (2014) and Marques et al (2015); and internationally, studies from Verhofstadt et al (2006), Reiner et al (2012) and Cousson-Gélie et al (2013).…”

“…Nakano et al (2002) found in a small sample of the Japanese population (40 couples), a factorial structure of 2 factors, where the depth and social support subscales were combined; Verhofstadt, Buysse, Rossel and Peene (2006) conducted a study with 286 Belgian couples and concluded that the original three-factor structure was the most suitable; Reiner, Beautel, Skaletz, Brahler and Stobel-Richter (2012), with a sample of 1494 adults, conducted the German validation of this scale, that also confirmed the tri-factorial structure of the QRI; Cousson-Gélie et al (2013) performed a confirmatory factor analysis, in France, with 388 cancer patients, which also corroborated the original factorial structure.…”

Dimensional Latent Structure of Relationship Quality: Results of Three Representative Population Samples

“…Representative samples of the German population were recruited in 1999 (Sample 1, using the Partnership Questionnaire [PFB; Kliem, Kröger, Stöbel‐Richter, Hahlweg, & Brähler, 2012]), 2009 (Sample 2, using the German version of the Quality of Relationship Inventory [QRI]; Reiner, Beutel, Skaletz, Brähler, & Stöbel‐Richter, ), and 2010 (Sample 3, using the short form of the PFB [the PFB‐K; Kliem, Job, et al, 2012) with assistance from an independent agency that specializes in market, opinion, and social research (USUMA, Berlin, Germany; see http://www.usuma.com/). A three‐stage random sampling procedure was used to select (a) sample point regions from 258 regions that were determined on the basis of representative data, (b) target households within sample point regions using a random‐route procedure, and (a) target persons within target households according to a Kish selection grid.…”

“…The response rate in Sample 2 (see Reiner et al, , for details) of those contacted was approximately 61.9%. The sample consisted of 2,520 German adults.…”

Father Involvement and Toddlers' Behavior Regulation: Evidence from a High Social Risk Sample

“…It has proven useful in both clinical and nonclinical research on close relationships and has been validated in other languages (Reiner, Beutel, Skaletz, Brähler & Stöbel-Richter, 2012).…”
