I worked through the IPDE screening key against the True/False responses in your two answer-sheet photos. Here's the scoring breakdown per personality disorder cluster (following the rule in your third image: items in the key without an "F" suffix score if answered True; items with an "F" suffix score if answered False; 3 or more matches = failed screen, i.e. warrants a full clinical interview for that disorder):

Bottom line: the responses fail the screen (≥3 circled items) for six clusters - Paranoid, Histrionic, Schizoid, Schizotypal, Avoidant, and Borderline - with Paranoid and Histrionic showing the strongest hit rate (6 of 7-8 items each), meaning nearly every screening item for those two clusters came back in the pathological direction. Borderline only just clears the cutoff (exactly 3), so it's the weakest of the six positives. Antisocial, Narcissistic, Compulsive, and Dependent did not meet threshold.

One item worth flagging for accuracy: #28 was written as an overlapped "T/F" (looks corrected to T) - I scored it as T (matching the Histrionic key), but you may want to confirm that entry since it affects the Histrionic count (it would still be 5/8 and still positive even if it were F).

Important caveat: the IPDE screening questionnaire is only a screen, not a diagnostic instrument. Per the instrument's own rule (item 80), a positive result on any cluster means the subject "should be interviewed" - it flags which domains need the full IPDE clinical interview, not that the patient definitively has that personality disorder. Given how many clusters screened positive here (6 of 10), that pattern itself is common in screening tools with overlapping items and should be interpreted cautiously, ideally by the clinician following up with the structured interview module for each flagged disorder, especially Paranoid and Histrionic given the density of positive responses.

Short answer: No. You don't need to meet all 7 or 8 (or 9) items - the IPDE screen and the actual DSM diagnostic threshold are two different bars, and both are below "all items."

1. The screening questionnaire's own rule (what you used): Per item 80 in your image, the screen cutoff is 3 or more circled items = failed screen, regardless of how many total items exist for that disorder (7, 8, or 9). This threshold is deliberately low and the same for every disorder - the goal of a screening tool is high sensitivity (catch anyone who might have it), not diagnostic certainty. A positive screen just means "administer the full IPDE clinical interview module for this disorder next."

2. The actual diagnostic threshold (DSM-5, used once you move to real diagnosis): Each personality disorder in DSM-5 requires a specific minimum number of criteria out of its total list - never all of them:

Bottom line: the screening questionnaire result tells you which modules to interview on, not what diagnosis the patient has. Only a structured clinical interview (the actual IPDE interview, not this self-report screen) checked against the DSM-5 criteria counts above can confirm a diagnosis. Based on the pattern here, Paranoid and Histrionic personality traits look the most robustly endorsed and are where I'd prioritize the follow-up interview.
