Is 「悩まされている 」a 使役受身形


In a Grammar book, they are introducing the 使役受身形 with the example, 感心させられる
But they also classified this sentence

> 隣の家の騒音に悩まされている

in this grammar structure too. But my Jisho told me that 悩まされる is the 受身 form
of 悩ます。

So, is 「悩まされている 」a 使役受身形? If not, why would they classified it in the same
group of させられる？




There is something called "shortened causative form" in Japanese. For example
you can say 走らす instead of 走らせる. See [Tae Kim's guide on this
topic](http://www.guidetojapanese.org/learn/grammar/causepass).

Although the article says the shortened causative form is rare and slangy,
it's not rare nor rough when godan verb's causative-passive form is
concerened. To my ears, the shortened causative-passive form ( _-asareru_ )
sounds considerably more common and natural than the "standard" causative-
passive ( _-aserareru_ ), even in formal writings.

  * 書かされる is more natural than 書かせられる
  * 笑わされる is more natural than 笑わせられる
  * 悩まされる is more natural than 悩ませられる

(I think this does not apply for shortened causative of ichidan verbs and
godan verbs with su-ending; 食べさされる and 話さされる are ungrammatical)

Some shortened (non-passive) causative forms are widely used without sounding
rough/slangy (eg 頭を悩ます問題, 犯人を泳がす, 醤油を切らす), and dictionaries often list them as
separate transitive godan verbs. In Japanese, the borderline of "the
causative-form of an intransitive verb" and "a transitive verb" can be
sometimes blurry. Nevertheless, I think it's not wrong to say 悩まされている is
causative-passive(-progressive).
