Abstract
Según la teoría interpersonal del suicidio, la pertenencia frus-
trada y la carga percibida son elementos clave en el desarrollo de la idea-
ción suicida. El Cuestionario de necesidades interpersonales (INQ) fue di-
señado para evaluar el grado de frustración de estas dos necesidades inter-
personales relacionadas con la ideación suicida. El objetivo de este estudio
fue analizar las propiedades psicométricas de una adaptación al español del
INQ-12 en pacientes con fibromialgia. Un análisis factorial exploratorio (n
= 180) y un análisis factorial confirmatorio (n = 179) fueron realizados en
dos submuestras seleccionadas al azar. El primer análisis llevó a la elimina-
ción de dos ítems, mientras que el segundo confirmó el ajuste de la estruc-
tura propuesta de dos factores. La fiabilidad estimada mediante el coefi-
ciente alfa de Cronbach y el coeficiente Spearman-Brown fue adecuada.
Para obtener evidencias de validez basadas en la relación con otros varia-
bles, se utilizaron tres variables relacionadas con el suicidio. Además, se uti-
lizó un grupo control (n = 99) para contrastar los promedios de las pun-
tuaciones INQ como evidencia de validez basada en puntajes diferenciales.
Estos hallazgos respaldan la utilidad de la versión española del INQ-10 pa-
ra evaluar el grado de frustración de estas necesidades interpersonales en
pacientes con fibromialgia
According to the interpersonal theory of suicide, thwarted be- longingness and perceived burdensomeness are key elements in the devel- opment of suicidal ideation. The Interpersonal Needs Questionnaire (INQ) was developed to assess the degree of frustration of these two in- terpersonal needs related to suicidal ideation. This study aims to analyze the psychometrics properties of a Spanish adaptation of INQ-12 in fi- bromyalgia patients. Exploratory factor analysis (n = 180) and confirmato- ry factor analysis (n = 179) were performed in two randomly selected sub- samples. The first analysis leads to the elimination of two items, whereas the second one confirmed the fit of the proposed two-factor structure. The reliability estimated using the Cronbach ́s alpha coefficient and the Spearman-Brown coefficient was adequate. To obtain further validity evi- dence based on the relationship with other variables three variables were used. Moreover, a control group (n = 99) was used to contrast the means of INQ scores as evidence of validity based on differential scores. These findings support the usefulness of the Spanish version of the INQ-10 for assessing the degree of frustration of these interpersonal needs in patients with fibromyalgia.
