Simple example datasets for ABCDs

Source: R/abcd.R

This are three (nested) datasets illustrating the logic model of change for a simple condom use intervention in a way that can be visualised using the abcd function. The full dataset is abcd_specs_full, a subset that does not explicitly include the conditions for effectiveness (instead showing letters that can then be explained in, for example, the manuscript text) is called abcd_specs_without_conditions, and a version that only contains the information about one sub-behavior (performance objective) is available as abcd_specs_single_po_without_conditions. The variables in the full dataset are:

data(abcd_specs_complete)

data(abcd_specs_without_conditions)

data(abcd_specs_single_po_without_conditions)

data(abcd_specification_example_xtc)

data(abcd_specs_dutch_xtc)

data(abcd_specification_empty)

Format

For abcd_specs_complete, a data frame with 7 variables and 7 rows; for abcd_specs_without_conditions, a data frame with 6 variables and 7 rows; for abcd_specs_single_po_without_conditions, a data frame with 5 variables and 4 rows; for abcd_specification_example_xtc and abcd_specs_dutch_xtc, a data frame with 7 variables and 5 rows' and for abcd_specification_empty, a data frame with 7 variables and 1 row.

Details

  • Behavior Change Principles: The behavior change principles (BCPs), also known as methods for behavior change or 'behavior change techniques' (BCTs), that describe the psychological principles that are assumed to realise the change in the (sub-)determinants.

  • Conditions for effectiveness\\n(e.g. parameters for use): The conditions for effectiveness that describe the constraints and considerations taken into account in the translation of the BCPs to practical applications for the relevant target population, context, culture, etc.

  • Applications: The applications of these BCPs. Where the BCPs describe theoretical principles, the applications are more or less tangible intervention elements.

  • Sub-determinants\\n(e.g. beliefs; can be formulated as Change Objectives): The specific aspects of teh target population's psychology that are targeted by the BCPs (e.g. beliefs, or in Intervention Mapping vocabulary, Change Objectives).

  • Determinants: The determinants, psychological constructs, that the targeted sub-determinants are a part of, and that together predict the Performance Objectives (sub-behaviors).

  • Performance Objectives: Explicitly defined sub-behaviors at a level of specificity that distinguishes them from other sub-behaviors, and that together form the target behavior.

  • Target Behavior: The ultimate target behavior, usually defined at a relatively general level.

In addition to these three datasets, a Dutch example specification is included named abcd_specs_dutch_xtc, and the same in English as abcd_specification_example_xtc.

Finally, abcd_specification_empty is an empty 'template' ABCD matrix.
