 Derivatives are available for all Lifelines versions of the MINI.\\
-Note that MINI v1 differs significantly from the other versions in that the available derivatives pertain to 'last year' instead of 'current' diagnoses and were made in [[https://www.r-project.org/|R]]. For all other versions derivates have been calculated using SPSS syntax.\\
+Note that MINI v1 differs significantly from the later versions. Specifically, its derivatives are based on diagnoses from the **previous year**, whereas other versions focus on **current** diagnoses.\\
 For the (digital) MINI v4 used in assessment [[2A]], items that were subdivided from the original MINI v2-v3 items were rejoined, which made calculations of derivatives and comparison with the other versions possible.\\

-===== 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 criteria, and 2) update of availability of MINI derivatives.
 === 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.
-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 present. Additionally, 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 a 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 corrected, resulting 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_2; mini_anyipp_adu_c_1 -> mini_anyipp_adu_c_2; mini_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
