No, these titles are not used in either the Scottish Parliament or the Welsh Senedd. The predominant reason for this is that there is no restriction in these chambers about referring to members by name - in the House of Commons, this is prohibited - the only time a member is mentioned by name is when they are disciplined (or "named") by the chair. MPs, therefore, began referring to each other as 'the honourable member for X'.
Proof of this can be found when speakers at these bodies accidentally slip into referring to members in this style, and are subsequently admonished by the chair. For example, in the Welsh Senedd:
Adam Price AM: Leader of the house, I was wondering if you could say whether Government colleagues have indicated to you yet when we
can expect the statement on the Circuit of Wales that we’ve been
promised by the First Minister before the end of the
month—[Interruption.] Would the honourable Member for Blaenau Gwent—?
If he has anything to say, he can get up and say it—
The Llywydd (Presiding Officer): Let me tell the honourable Member—who’s not particularly honourable, as no Member in this
Chamber, to repeat myself, is an honourable Member—but, yes, please,
the business Minister requires no help from other Ministers in
answering business questions. Adam Price.
Plenary meeting - 13/06/2017
And in the Scottish Parliament:
Danny Alexander: I do not think that—sorry, but I am not sure
how one addresses an MSP; in Westminster we say “the honourable
member”. Do I call you Mr FitzPatrick?
Joe FitzPatrick: Joe is fine.
David Whitton (Strathkelvin and Bearsden) (Lab): We call him lots of
other things.
The Convener: We stand on ceremony, but don’t stand on ceremony.
