Theoretical background

This new symptom validity assessment instrument includes two scales. A Scale containing Genuine Symptoms Subscales (Cognitive Symptomatology; Depressive Symptomatology; Pain Symptomatology; Somatic Symptomatology; Anxious Symptomatology) and a Scale that includes Pseudo-Symptoms Subscales (Cognitive; Motor; Sensory; Pain; Anxiety/Depression), as well as items that measure the consistency of responses and items that evaluate cooperation. With this framework, the SRSI seeks to address known limitations underlying the use of other instruments oriented towards the symptom validity assessment (eg, SIMS).

Description

Assessment Domain: Symptom validity.

Type of Instrument: Paper-and-pencil test.

Administration: Individual, 10-15 minutes.

Age range: 18 + years.

Studies

Portuguese empirical studies with the SRSI are supported by investigations associated with several master's dissertations: seven have already been completed (Domingues, 2019; Dwarkadas, 2018; Morais, 2022; Pinheiro, 2019; Silva, 2022; Venâncio, 2021). More specifically, the investigations include a normative study, three validation studies in a prison context (one of which is in preparation), two validation studies through an analogous simulation design (community sample, prison sample) and a validation study in medico-legal context. A synthesis of the three studies implemented in a prison context was recently published (Silva et al., 2023).

The Self-Report Symptom Inventory (SRSI) assessment (and validation) protocols include Portuguese versions of the following instruments: Structured Inventory of Malingered Symptomatology (SIMS), Symptom Validity Scale – Version 2 (EVS-2), Beck Depression Inventory – II (BDI-II), State-Trait Anxiety Inventory (STAI Form Y1 – Y2), Brief Symptom Inventory (BSI), Eysenck Personality Questionnaire - Revised (EPQ-R), Brief Pain Inventory (BPI), Self-Report Psychopathy Scale – Short Form (SRP-SF), Social Desirability Scale (EDS-20), in addition to a Sociodemographic Questionnaire and a Post-Experimental Questionnaire (used in studies of analogue design).
