-===== Mini update March 2025 ===== +\\ 
-March 2025, an updated version of the mini derivatives ​has been added to the Lifelines catalogue. This updated version included ​two aspects: 1) fix of coding error in the original script for panic disorder ​diagnosis, 2) update of availability of mini derivatives.+===== MINI update ​March 2025 ===== 
 +In March 2025, an updated version of the MINI derivatives ​was added to the Lifelines catalogue. This update ​ includes ​two major changes: 1) correction ​in panic disorder ​diagnostic criteriaand 2) update of availability of MINI derivatives.
  
 === 1. Panic Disorder Diagnostic Criteria update === === 1. Panic Disorder Diagnostic Criteria update ===
 To meet diagnostic criteria for Panic Disorder, individuals must experience at least four out of thirteen possible additional symptoms during their panic attacks according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Therefore, an individual that reports reporting that at least ten of these symptoms **are not present during an attack**, cannot meet diagnostic criteria for Panic Disorder and should be coded as a control. ​ To meet diagnostic criteria for Panic Disorder, individuals must experience at least four out of thirteen possible additional symptoms during their panic attacks according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Therefore, an individual that reports reporting that at least ten of these symptoms **are not present during an attack**, cannot meet diagnostic criteria for Panic Disorder and should be coded as a control. ​
  
-A coding error in the original diagnostic script incorrectly classified participants as controls if they reported ​≥4 symptoms not present ​during attacks, instead of the correct threshold of ≥10 symptoms not presentAdditionally, participants with missing data on any symptom were mistakenly assigned ​"​NA"​ for their Panic Disorder ​diagnostic status. +However, ​the original diagnostic script ​contained an error: it incorrectly classified participants as controls if they reported ​four or more symptoms ​as not present, instead of the correct threshold of ≥10. ​Moreover, participants with missing data on any symptom were mistakenly assigned ​diagnostic status ​of “NA.” These issues ​have now been corrected resulting in
- +  * A revised variable for Panic Disorder ​diagnosis with a higher number of identified cases 
-These errors ​have been correctedresulting in an updated ​Panic Disorder ​variable and a higher number of subjects with PD. Consequently,​ the variables assessing "any anxiety problems"​ and "any internalizing problems"​ have also been updated to reflect these corrections. ​ +  * Corresponding updates to related ​variables, including: 
-__Resulting ​variables:__ to reflect this correction, the corresponding variables are presented in a version 2 variant (mini_anyanx_adu_c_1 -> mini_anyanx_adu_c_2mini_anyipp_adu_c_1 -> mini_anyipp_adu_c_2mini_pd_adu_c_1 -> mini_pd_adu_c_2).\\+         ​- ​mini_anyanx_adu_c_1 -> mini_anyanx_adu_c_2 ​(any anxiety problems) 
 +         ​- ​mini_anyipp_adu_c_1 -> mini_anyipp_adu_c_2 ​(any internalizing problems) 
 +         ​- ​mini_pd_adu_c_1 -> mini_pd_adu_c_2 ​(panic disorder) 
 +\\ 
 +=== 2. Updated availability of MINI derivatives === 
 +In addition to correcting the coding error, the script has been adapted to match the new data release structure, including a conversion to the updated variable names. This has allowed for the inclusion of additional participants in the dataset:  
 +  * Assessment 1A: ~200 newly coded participants 
 +  * Assessment 2A: >10,000 additional participants (from incomplete release to finished release) 
 +  * Assessment 3A: newly added for all participants
 \\ \\
-=== 2. Update availability mini derivatives === 
-Besides the resolvement of the coding error, the script has been converted to the new data release, providing a transition to the new variable names. Using this updated script, additional participants have been added to the available coded data: 
-  * Assessment 1A: ~200 new cases 
-  * Assessment 2A: >10 000 new cases (from incomplete release to finished release) 
-  * Assessment 3A: newly added
