Abstract
In psychological injury and related forensic evaluations, two types of tests are commonly used to assess Negative Response
Bias (NRB): Symptom Validity Tests (SVTs) and Performance Validity Tests (PVTs). SVTs assess the credibility of self-
reported symptoms, whereas PVTs assess the credibility of observed performance on cognitive tasks. Compared to the large
and ever-growing number of published PVTs, there are still relatively few validated self-report SVTs available to professionals
for assessing symptom validity. In addition, while several studies have examined how to combine and integrate the results of
multiple independent PVTs, there are few studies to date that have addressed the combination and integration of information
obtained from multiple self-report SVTs. The Special Issue of Psychological Injury and Law introduced in this article aims
to help fill these gaps in the literature by providing readers with detailed information about the convergent and incremental
validity, strengths and weaknesses, and applicability of a number of selected measures of NRB under different conditions
and in different assessment contexts. Each of the articles in this Special Issue focuses on a particular self-report SVT or set of
SVTs and summarizes their conditions of use, strengths, weaknesses, and possible cut scores and relative hit rates. Here, we
review the psychometric properties of the 19 selected SVTs and discuss their advantages and disadvantages. In addition, we
make tentative proposals for the field to consider regarding the number of SVTs to be used in an assessment, the number of
SVT failures required to invalidate test results, and the issue of redundancy when selecting multiple SVTs for an assessment.

The expression negative response bias (NRB) refers
to a tendency to generate less implied healthy or more
pathological test results than would be expected based on the
overall level of adjustment of the test-taker (Dyonisus et al.,
2011; Franzen & Iverson, 2000; Rogers & Bender, 2018).
In contrast to terms that have a motivational component,
such as malingering or deception, NRB constitutes a
response style on instruments, without any inference of
motivation. Another term often used to achieve a similar
non-inferential connotation is overreporting (Ben-
Porath, 2013). However, we argue that NRB likely has
an even broader meaning, as it encompasses both the

overreporting (or overstatement) of experienced problems
and the underreporting (or understatement) of psychological
resources and strengths. In addition, we would also like to
point out that NRB is distinct from both positive response
bias, in which the examinee tries to look overly healthy
or good, and content-unrelated distortion, in which
the content of the item(s) or task(s) is not the reason the
examinee does not respond in an appropriate or truthful
manner to it. Definitional issues aside, it is now agreed that
the credibility of presented psychological problems cannot
be taken for granted in forensic and related assessment
contexts, and that the possibility of NRB should always be
considered when conducting forensic assessments (Sherman
et al., 2020; Sweet et al., 2021).
To determine whether NRB is present, professionals
should use multiple sources of information (APA, 2013;
Sweet et al., 2021). With regard to psychological tests,
Larrabee (2012) described two types of instruments that
address NRB. Tests evaluating the credibility of self-
reported symptoms are considered Symptom Validity
