Question

What is the best measure to assess paranoid ideation ???​

Answer 1

Answer:

There are many scales for paranoid ideation but the choice depends from the aims of your research: Paranoid Thoughts Scale (Green et al., 2008); Paranoia Scale (Fenigstein and Vanable, 1992), Psychotic Symptoms Rating Scale (Haddock et al., 1999) and paranoid items of the PDI (Peters et al., 1999). For assessing the insight of ideation you can use the Brown Assessment of Beliefs Scale (BABS; Eisen et al., 1998).

Answer 2

Indeed, not evidencing the clinical

relevance of items has been a criticism when assessing other constructs in the general

population, such as obsessive-intrusive thoughts (Berry & Laskey, 2012). Furthermore,

questionnaires validated clinically and non-clinically have greater potential utility. Psychotic-

like experiences that occur without significant distress or impairment increase the later risk of

symptoms that may warrant a clinical diagnosis. Thus, assessing paranoia across clinical and non-clinical

populations could highlight variables that increase the likelihood of paranoia-related distress.

Questionnaires validated for use with individuals experiencing distressing paranoia could also

be used clinically within assessment or for outcome measurement within interventions.
