Screening the risk of bipolar spectrum disorders: Validity evidence of the Mood Disorder Questionnaire in adolescents and young adults

Latent profile analysis of psychosis liability in a community‐derived sample of adolescents: Links with mental health difficulties, suicidal ideation, bipolar‐like experiences and psychotic‐like experiences

“…and schizotypal traits(Cella et al, 2013;Denovan et al, 2018;Fonseca-Pedrero, Ortuno-Sierra, et al, 2016;Hori et al, 2014;Tabak & Weisman de Mamani, 2013;Wang et al, 2017).Although there is heterogeneity in the measures used and the nature of the samples, previous studies conducted in adolescent population are clearly convergent with the results found in this study. For instance,Cella et al (2013), through the sO-LIFE and a sample of adolescents, reported three-classes (low schizotypy, an unusual subjective experiences, and true schizotypy) similar to those found in the present research.…”

“…It is relevant to note that schizotypy, as a multidimensional and complex construct, allow us to identify these subgroups and to take into account the multiple expression of the psychosis phenotype (positive, negative and disorganization) rather than only the positive dimension of this phenotype (Pignon et al, ). Previous studies have examined the latent structure across all psychotic spectrum such as psychotic symptoms (Kendler et al, ; Pignon et al, ), schizotypal personality disorder (Fossati et al, ), subclinical psychosis symptoms (Ryan et al, ; Valmaggia et al, ), PLEs (Ahmed et al, ; Cella et al, ; Gale et al, ; Shevlin et al, ) and schizotypal traits (Cella et al, ; Denovan et al, ; Fonseca‐Pedrero, Gooding, Ortuño‐Sierra, & Paino, ; Fonseca‐Pedrero, Ortuno‐Sierra, et al, ; Hori et al, ; Tabak & Weisman de Mamani, ; Wang et al, ). Although there is heterogeneity in the measures used and the nature of the samples, previous studies conducted in adolescent population are clearly convergent with the results found in this study.…”

“…A result is considered positive if the participant replies affirmatively to 7 or more items of the 13 proposed and if, in addition, the symptoms described occurred during the same time period (criterion 2) and represented moderate or severe problems (criterion 3). In this study, we used the Spanish version validated in adolescents and young adults (Fonseca‐Pedrero, Ortuño‐Sierra, et al, ).…”

“…The PQ‐B asks additional questions regarding the extent/severity of impairment and distress, rated on Likert‐type (1 = Strongly disagree to 5 = Strongly agree). The Spanish adaptation of the PQ‐B has demonstrated adequate psychometric properties (Fonseca‐Pedrero, Gooding, Ortuño‐Sierra, & Paino, ; Fonseca‐Pedrero, Gooding, Ortuño‐Sierra, Pflum, et al, ; Fonseca‐Pedrero, Ortuño‐Sierra, et al, ).…”

Validation of the Prodromal Questionnaire–Brief in a representative sample of adolescents: Internal structure, norms, reliability, and links with psychopathology
