Title: | Tools for Behavior Change Researchers and Professionals |
---|---|
Description: | Contains specialised analyses and visualisation tools for behavior change science. These facilitate conducting determinant studies (for example, using confidence interval-based estimation of relevance, CIBER, or CIBERlite plots, see Crutzen, Noijen & Peters (2017) <doi:10/ghtfz9>), systematically developing, reporting, and analysing interventions (for example, using Acyclic Behavior Change Diagrams), and reporting about intervention effectiveness (for example, using the Numbers Needed for Change, see Gruijters & Peters (2017) <doi:10/jzkt>), and computing the required sample size (using the Meaningful Change Definition, see Gruijters & Peters (2020) <doi:10/ghpnx8>). This package is especially useful for researchers in the field of behavior change or health psychology and to behavior change professionals such as intervention developers and prevention workers. |

This function generates an acyclic behavior change diagram (ABCD) from a specification in a google sheet or .csv file. An ABCD is a logic model that illustrates the assumptions underlying a behavior change intervention. Specifically, the ABCD shows the assumed causal and structural assumptions, thereby showing what is assumed to cause what (e.g. which elements of the intervention are assumed to influence which aspects of the target population's psychology?) and what is assumed to consist of what (e.g. which determinants are assumed to contain which specific aspects of the target population's psychology?).

Specifically, a full ABCD is a model that shows the following elements:
Behavior Change Principles (BCPs): The specific psychological principles engaged to influence the relevant sub-determinants, usually selected using the determinants to which the sub-determinants 'belong'. These are also known as methods of behavior change in the Intervention Mapping framework, or behavior change techniques, BCTs, in the Behavior Change Wheel approach. For a list of 99 BCPs, see Kok et al. (2016).
Conditions for effectiveness: The conditions that need to be met for a Behavior Change Principle (BCP) to be effective. These conditions depend on the specific underlying Evolutionary Learning Processes (ELPs) that the BCP engages (Crutzen & Peters, 2018). If the conditions for effectiveness (called parameters for effectiveness in the Intervention Mapping framework) are not met, the method will likely not be effective, or at least, not achieve its maximum effectiveness.
Applications: Since BCP's describe aspects of human psychology in general, they are necessarily formulated on a generic level. Therefore, using them in an intervention requires translating them to the specific target population, culture, available means, and context. The result of this translation is the application of the BCP. Multiple BCPs can be combined into one application; and one BCP can be applied in multiple applications (see Kok, 2014).
Sub-determinants: Behavior change interventions
engage specific aspects of the human psychology (ideally, they
specifically, target those aspects found most important in
predicting the target behavior, as can be established with
CIBER
plots. These aspects are
called sub-determinants (the Intervention Mapping framework
references Change Objectives, which are sub-determinants
formulated according to specific guidelines). In some
theoretical traditions, sub-determinants are called beliefs.
Determinants: The overarching psychological constructs that are defined as clusters of specific aspects of the human psychology that explain humans' behavior (and are targeted by behavior change interventions). Psychological theories contain specific definitions of such determinants, and make statements about how they relate to each other and to human behavior. There are also theories (and exists empirical evidence) on how these determinants can be changed (i.e. BCPs), so althought the sub-determinants are what is targeted in an intervention, the selection of feasible BCPs requires knowing to which determinants those sub-determinants belong.
Performance objectives: The specific sub-behaviors that often underlie (or make up) the ultimate target behavior. These are distinguished from the overarching target behavior because the relevant determinants of these sub-behaviors can be different: for example, the reasons why people do or do not buy condoms can be very different from the reasons why they do or do not carry condoms or why they do or do not negotiate condom use with a sexual partner.
Behavior: The ultimate target behavior of the intervention, usually an umbrella that implicitly contains multiple performance objectives.
For details, see Peters et al. (2019).

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)
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)
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.
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.

This function generates a high-level plot consisting of several diamond plots. This function is useful for estimating the relative relevance of a set of determinants of, for example, behavior. The plot in the left hand panel shows each determinant's distribution with a diamond representing the confidence interval. The right hand plot shows the determinants' associations to one or more 'target' variables, such as behavior or determinants of behavior.

COMPLECS was developed to help make sense of complex systems. It reads data from a number of worksheets in a spreadsheet and generates a diagram according to those specifications. Originally, COMPLECS was developed to visualise a problem during the needs assessment phase of intervention development.

Only entities with the following entity types are used from the COMPLECS specification:
person
organization
environmental_condition
behavior
determinant
outcome
Furthermore, it will be assumed that the only direct connections from
behavior
entities to outcome
entities belong to the focal population;
therefore, if behaviors of environmental actors are important for an
outcome, those behaviors' effects must be represented as
environmental_condition
entities - otherwise the relevant person
s or
organizations
s will be erroneously considered as focal population members.

These functions compute the Potential for Change Index for one or multiple
(sub-)determinants, the room for improvement (an intermediate estimate),
and produce a convenient table with an overview of all (sub-)determinants.
Note that for determinant selection purposes, quantitative estimates such
as the Potential for Change Index should never be used without also
thoroughly inspecting the visualisations of the univariate distributions
and the confidence intervals for the associations to the ultimate
intervention targets (usually the target behavior or a proxy measure). For
this purpose, the Confidence Interval-Based Estimation of Relevance plots
can be used (see CIBER()
).

The Potential for Change index was developed by Keegan et al. and is a
numerical representation of a number of important features in CIBER()
plots (for more details, please see the references below). It turned out
a similar measure, the Intervention Potential, was developed by Huber &
Mosler (2013). The latter uses regression coefficients as weights, which
is problematic for a number of reasons (see Crutzen, Peters & Noijen, 2017),
and has therefore not been implemented as a default, but it is possible to
use regression coefficients by specifying a custom weight function.
The original Potential for Change Index was conceptualized to optimize intervention tailoring and improve the prediction of individual-level intervention effectiveness. A second conceptualization of the Potential for Change Index can facilitate sub-determinant selection.
In addition to using the minimum
, maximum
, center
, and weight
functions to specify custom functions, specific types have also been
implemented to quickly use a prespecified combination of functions.
The first (type = '1'
) is computed as follows:
For sub-determinants with a positive zero-order correlation with behavior, the sample mean is subtracted from the observed maximum score, and the result is multiplied by the zero-order correlation;
For sub-determinants with a negative zero-order correlation with behavior, the sample mean is subtracted from the observed minimum score, and the result is multiplied by the zero-order correlation.
The second (type = '2'
) is computed as follows:
For sub-determinants with a positive zero-order correlation with behavior, the sample mean is subtracted from the .95 quantile of the scores, and the result is multiplied by the squared zero-order correlation (i.e. the proportion of explained variance);
For sub-determinants with a negative zero-order correlation with behavior, the sample mean is subtracted from the .05 quantile of the scores, and the result is multiplied by the squared zero-order correlation (i.e. the proportion of explained variance);
The second variant effectively takes the 5% trimmed maximum and minimum, rendering it less sensitive to outliers, penalizes weak associations with behavior more severely, and decreases sensitivity to differences between correlations. These differences should render the second variant a bit more robust over different samples.
The room for improvement is one of the ingredients of the Potential for Change Index or P_delta, a generalized version of the Intervention Potential. The Determinant Selection Table efficiently presents the Potential for Change Indices for a set of (sub-)determinants.
For the individual-level version, a vector or data frame with the same dimensions as provided; for the sample-level version, if a vector is provided, a single number, and if a data frame is provided, a vector with as many values as the data frame has columns. For Determinant Selection Table, a data frame.

d |
The value of Cohen's d. |
cer |
The Control Event Rate. |
r |
The correlation between the determinant and behavior (for mediated Numbers Needed for Change). |
n |
The sample size. |
threshold |
If the event rate is not available, a threshold value can
be specified instead, which is then used in conjunction with the mean
( |
mean |
The mean value, used to draw the plot, or, if no CER is provided but instead the threshold value, to compute the CER. |
sd |
The standard deviation, used to draw the plot (and to compute the CER if a threshold value is supplied instead of the CER). |
poweredFor |
The Cohen's d value for which the study was powered. This expected Cohen's d value can be used to compute the threshold, which then in turn is used to compute the CER. To use this approach, also specify the mean and the standard deviation. |
thresholdSensitivity |
This argument can be used to provide a vector of potential threshold values, each of which is used to compute an NNC. This enables easy inspection of whether the value chosen as threshold matters much for the NNC. |
eventDesirable |
Whether an event is desirable or undesirable. |
eventIfHigher |
Whether scores above or below the threshold are considered 'an event'. |
conf.level |
The confidence level of the confidence interval. |
dReliability |
If Cohen's d was not measured with perfect reliability,
|
d.ci |
Instead of providing a point estimate for Cohen's d, a confidence interval can be provided. |
cer.ci |
Instead of providing a point estimate for the Control Event Rate, a confidence interval can be provided. |
r.ci |
Instead of providing a point estimate for the correlation, a confidence interval can be provided. |
d.n |
In addition to providing a point estimate for Cohen's d, a sample size can be provided; if it is, the confidence interval is computed. |
cer.n |
In addition to providing a point estimate for the Control Event Rate, a sample size can be provided; if it is, the confidence interval is computed. |
r.n |
In addition to providing a point estimate for the correlation, a sample size can be provided; if it is, the confidence interval is computed. |

Numbers Needed to Treat is a common and very useful effect size
measure in use in the medical sciences. It is computed based on the
Control Event Rate (CER) and the Experimental Event Rate (EER), and
expresses how many people would need to received a treatment to yield
a beneficial result for one person. In behavior change research, a
similar measure would be useful, but the outcome is normally not
dichotomous as is common in the medical literature (i.e. whether a
participants survives or is cured), but continuous. Numbers Needed
for Change fills this lacuna: it is simply the Numbers Needed to Treat,
but converted from a Cohen's d value. nnt
is an alias for nnc
.
For more details, see Gruijters & Peters (2019) for details.

The behaviorchange::opts
object contains three functions to set, get, and reset
options used by the escalc package. Use behaviorchange::opts$set
to set options,
behaviorchange::opts$get
to get options, or behaviorchange::opts$reset
to reset specific or
all options to their default values.
opts
opts
An object of class list
of length 4.
It is normally not necessary to get or set behaviorchange
options.
The following arguments can be passed:
For behaviorchange::opts$set
, the dots can be used to specify the options
to set, in the format option = value
, for example,
EFFECTSIZE_POINTESTIMATE_NAME_IN_DF = "\n"
. For
behaviorchange::opts$reset
, a list of options to be reset can be passed.
For behaviorchange::opts$set
, the name of the option to set.
For behaviorchange::opts$get
, the default value to return if the
option has not been manually specified.
To see the full list of options and their default values,
use behaviorchange::opts$default()
. Some examples are:
A color theme for abcd()
.
The worksheet and columns names for complecs()
.
Whether to be chatty or silent.

represent all participants that made it past a given behavior.
The behaviors of the Party Panel waves were:
2015: Behaviors related to using highly dosed ecstasy pills
2016: Behaviors related to visiting nightlife first-aid facilities
2017: Behaviors related to hearing protection
2018: Behaviors related to flirting and boundary crossing
2019: Behaviors related to sleeping hygiene surrounding nightlife participation
