Data

Data sets of dyadic data for use with dySEM

These data sets come from a variety of sources, and are used to facilitate the exemplar deployment of dySEM functionality; they may be useful to you for learning, teaching, and/or development.

commitmentM: Ratings of relational satisfaction and commitment from 282 (M)ixed-sex couples
commitmentQ: Ratings of relational satisfaction and commitment from 282 (Q)ueer couples
DRES: Relationship quality and sexual satisfaction of 121 couples
imsM: Ratings on the full Investment Model Scale (IMS) from 282 (M)ixed-sex couples
pnrqM: Ratings on items from the Positive-Negative Relationship Quality Scale (PNRQ; Rogge et al., 2017) from 219 (M)ixed-sex couples
prqcQ: Ratings on items from the Perceived Relationship Quality Components (PRQC) Inventory from 118 (Q)ueer couples

Scrapers

Scrape variable information from a dyadic data set

These functions are used to extract variable names and other information from dyadic data sets, to facilitate the specification of dySEM models.

scrapeVarCross(): A Variable Name-Scraping and Indexing Function for cross-sectional data

Scripters

Uni-construct Scripters

These functions are used to generate lavaan syntax corresponding to models representing one construct within a dyadic data set

scriptUni(): A Function That Writes, Saves, and Exports Syntax for Fitting Unidimensional Dyadic Factor Models
scriptCor(): A Function That Writes, Saves, and Exports Syntax for Fitting Correlated Dyadic Factor Models
scriptHier(): A Function That Writes, Saves, and Exports Syntax for Fitting Hierarchical Dyadic Factor Models
scriptBifac(): A Function That Writes, Saves, and Exports Syntax for Fitting Bifactor Dyadic Models

Bi-construct Scripters

These functions are used to generate lavaan syntax corresponding to models representing two constructs within a dyadic data set

scriptAPIM(): A Function That Writes, Saves, and Exports Syntax for Fitting Latent Actor-Partner Interdependence Models (APIMs)
scriptObsAPIM(): A Function That Writes, Saves, and Exports Syntax for Fitting Observed Actor-Partner Interdependence Models

Multi-construct Scripters

These functions are used to generate lavaan syntax corresponding to models representing more than two constructs within a dyadic data set

scriptCFA(): A Function That Writes, Saves, and Exports Syntax for Fitting Latent Dyadic Confirmatory Factor Analysis (CFA) Models with Multiple Factors

These functions are used to generate lavaan syntax corresponding to models that are used to make corrections to model fit indexes when fitting indistinguishable models

scriptISAT(): A Function That Writes, Saves, and Exports Syntax for Fitting the I-SAT model for indistinguishable dyads
scriptINULL(): A Function That Writes, Saves, and Exports Syntax for Fitting the I-NULL model for indistinguishable dyads
